In uart_nrf5.c the IRQ masks for the TX READY and ERROR events are
incorrect. This pull request fixes the mask values so they are
according to the nRF51/nRF52832/nRF52840 product specification.

uart_irq_tx_empty() function proved to be problematic: its semantics
was not documented properly, and many hardware uses terminology like
"TX register empty" to signify condition of TX register being ready
to accept another character (what in Zephyr is tested with
uart_irq_tx_ready()). To avoid confusion, uart_irq_tx_empty() was
renamed to uart_irq_tx_complete(), propagating to drivers/serial
device methods.
The semantics and usage model of all of uart_irq_rx_ready(),
uart_irq_tx_ready(), uart_irq_tx_complete() is now described in
detail.

Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99

To secure correct signal levels on the pins by the UART when
the system is in OFF mode, the pins must be configured in
the GPIO peripheral as described in nRF5 Product
Specification.
UART Pin, Direction, Output Value:
RXD, Input, NA
CTS, Input, NA
RTS, Output, 1
TX, Output, 1
This commit sets the RTS line to a initial value of 1.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

The new Nordic MDK redefines certain UART signal names for backwards
compatibility with the new nRF52840 IC.
This patch addresses the potential name conflict between the redefined
signals and the existing variable names defined in the UART driver.

PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.
New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.
Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

The Ready To Send (RTS) hardware flow control signal in the nRF5
UART was being configured as an output with a pull-up on it.
This was seemingly causing certain issues with btattach on Linux
and it's not done anywhere else.

The baudrate calculation present in set_baudrate() is
causing the UART to emit inital bytes incorrectly, for a
reason currently unknown, but directly related to the fact
that __aeabi_uldivmod is being invoked.
Since the nRF5x Product Specifications do not provide a
standard formula to calculate baudrates and instead list
a predefined set of divisor values, we opt here to use the
official values and remove the attempt at calculating them
manually.

Integrating the IRQ definitions for both nRF51 and nRF52, and defining

Also switch the controller, uart and clock drivers to use the common
header definitions.

The drivers config structure initializer sets sys_clk_freq statically.
The runtime repeated setup of sys_clk_freq is superfluous, and
inconsitent with const driver config structures.
