Coded PHY is only enabled by default if the application is using
BT_HCI_RAW.
Coded PHY is not needed in most applications.
By disabling Coded PHY, most applications will:
* Get smaller in terms of flash and ram usage
* Not get vurnerable to devices trying to switch to Coded and
thereby increasing power consumption.

Use TX FIFO level interrupt if available in hardware. It matches the
Zephyr UART API and avoids "bootstrapping" which is needed when using
the TX edge interrupt ("TI"). TX FIFO has room for up to 32 characters
and will typically reduce the number of interrupts.
Details:
APBUART can be synthesized with or without support for TX/RX FIFO.
Edge interrupts which fire when TX holding register changes and RX data
available are always available, independent of the FIFO configuration.
If FIFO is made available at synthesis time, two additional interrupts
become available: TX FIFO half-empty and RX FIFO half-full. These
are level interrupts.

This commit aligns the GRLIB APBUART driver with the Zephyr UART API
and fixes an issue where TX interrupt could previously be lost. It
was typically seen during interactive operation in the Zephyr shell.
There is an expectation in the Zephyr UART API that TX ready (i.e. TX
buffer space available) interrupt is a level interrupt, i.e. always
active while there's TX buffer space available. In particular, there's
an expectation that after uart_irq_tx_enable(), the TX interrupt will
immediately fire (assuming free TX buffer space is available).
The APBUART "Transmitter interrupt (CTRL_TI)" does not directly fulfill
this expectation because it is edge triggered and fires when the TX
holding register moves from being non-empty to empty. The solution
is to "bootstrap" interrupt processing by calling user-defined ISR
in irq_tx_enable().
This fix is similar to commit 49bb163756 ("drivers: serial:
uart_cmsdk_apb: Fix interrupt-driven operation").

Following the idiom used for system calls, add script support to read
the initial application binary to identify which devices are defined,
and to use their offset in the device array as their unique handle
rather than the externally-defined ordinal from devicetree. The
device dependency arrays are updated to use these handles.

Generate arrays of dependency information for each device. If a
device definition is being constructed from devicetree these come from
the devicetree dependency information. Additional dependencies may be
passed through using the DT_ macros.
Define flag values for device handles so we can partition the
dependency array into distinct sets, which include things it requires,
things it supports (may not be needed), and child nodes (not
implemented, may not be needed).

Timer 1 has two interrupts on STM32F0: TIM1_BRK_UP_TRG_COM_IRQn (13) and
TIM1_CC_IRQn (14). "brk" interrupt name does not reflect all the events
supported by the interrupt, so it has been renamed to "brk_up_trg_com".
On all other series except G0 timer 1 has a specific interrupt for each
event, so in such case "brk" is just fine.

ESP chip send number of available RX data using
+IPD=<sock>,<avail_bytes> command. This exact number (truncated to MRU)
was used to read data with AT+CIPRECVDATA=<sock>,<num_of_bytes>.
Use always MRU when sending AT+CIPRECVDATA=<sock>,<mru> request. When
there are less bytes available, then +CIPRECVDATA will just return less
bytes, which is fine for the driver.
There are two advantages to this new behavior:
* there is no need to follow how many bytes were notified by +IPD
message, thus reducing implementation size,
* when data is constantly received by ESP chip, then the last number of
bytes notified by +IPD is no longer up-to-date when sending a
AT+CIPRECVDATA; always requesting MRU number of bytes allows to
always receive maximum currently available number of bytes buffered
by ESP chip.

Dump of communication between ESP chip and Zephyr shows that
+IPD:<sock>,<bytes_avail> is always received after +CIPRECVDATA. This
means that we don't need to update sock->bytes_avail in esp_workq
thread. Additionally there is no need to schedule next AT+CIPRECVDATA
request, as that will be done by +IPD handler anyway.
Relying on +IPD to be received after each +CIPRECVDATA (as long as there
is some more data to be received) allows to simplify operations on
sock->bytes_avail. From now on only esp_rx thread will update its value
and schedule AT+CIPRECVDATA in esp_workq thread. Then in
sock->bytes_avail will be treated as "readonly" in esp_workq
thread. This allows to prevent race condition when both esp_rx and
esp_workq threads could potentially update value of sock->bytes_avail
value at the same time.
<sock>,CLOSED message is received always after retrieving all data from
ESP chip (using AT+CIPRECVDATA), so there is no need to check whether
there are more bytes to be received before marking socket as closed in
Zephyr driver.
