1. API function: uart_nrfx_irq_tx_enable is expected to enable and
trigger TXDRDY interrupt. Due to HW limiation before first byte has
been sent TXDRDY interrupt will not be triggered so it must be forced
by the software.
2. Common function: uart_nrfx_irq_tx_ready_complete is used for two
API entries: irq_tx_ready, irq_tx_complete because Nordic hardware does
not distinguish between them. This function returns 1 when driver is
ready to accept data and 0 otherwise.
3. Removed Hungarian prefixes.

Configure BlueNRG in controller w/o host.
By disabling 'HCI_reset' via the quirk, we can request to
BluesNRG hardware to be on controller mode just after it is ready.
By the way it's no necessary to manage a 'HCI_reset' when BluesNRG are
initialised (and on controler mode).

In order to avoid bytes dropping when RTT output buffer is full,

If host session is detected console retries after wait state
expecting host to empty the buffer. If host session is not detected
console drops the byte without retrying.

(Defined at
arch/x86/soc/intel_quark/quark_se/Kconfig.defconfig.series)
...that again depends on SPI_SLAVE
(This might not be a problem in practice, but it'd be difficult to
detect.)
I think the underlying issue is that SPI_2_NRF_SPIS 'select's SPI_SLAVE,
while SPI_2 'depends on' it.
Fix it by having SPI_2_NRF_SPIS 'depend on' SPI_SLAVE as well. This will
require SPI_SLAVE to be explicitly enabled before SPI_2_NRF_SPIS can be
enabled.
No configuration files in Zephyr itself seem to currently enable
SPI_2_NRF_SPIS (and it defaults to n), so no tweaks should be needed
there.

The various STM32 reference manuals sometimes define the USB endpoints
as IN or OUT only and sometimes as bidirectional, even in the same
manual. This is likely because the OTG implementation has one set of
registers for the IN endpoints and one other set for OUT endpoints.
However at the end a given endpoint address can both transmit and
receive data.
This causes some confusion how to declare the endpoints in the device
tree, and depending on the SoC, they are either the same number of IN
and OUT endpoints declared, or they are declared as bidirectional. At
the end it doesn't really matter given how the driver uses those values:
#define NUM_IN_EP (CONFIG_USB_NUM_BIDIR_ENDPOINTS + \
CONFIG_USB_NUM_IN_ENDPOINTS)
#define NUM_OUT_EP (CONFIG_USB_NUM_BIDIR_ENDPOINTS + \
CONFIG_USB_NUM_OUT_ENDPOINTS)
#define NUM_BIDIR_EP NUM_OUT_EP
This patch therefore cleanup the driver, the DTS, and the DTS fixups to
only define the number of bidirectional endpoints.
In addition to the cleanup, that fixes a regression introduced by commit
52eacf16a2 ("driver: usb: add check for endpoint capabilities"), which
introduced a wrong check for SoC only defining the number of
bidirectional endpoints.
