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.

riscv-qemu UART:
1) comprises only one register that is used to send or
receive characters in a polling fashion.
2) does not have a FIFO and is not interrupt-driven.

UART 16750 is basically a UART 16550 with a 64-bytes FIFO.
The 64-bytes FIFO can be enabled via register FCR.
Account for it in the uart_ns16550 driver whenever the
CONFIG_UART_NS16750 variable is set.

There was a misalignment between Zephyr UART device numbering and
SoC UART IP. Device "UART_1" was mapped to IP USART_2, which could
be confusing for user.
This commit allows to align "UART_1" to IP USART_1.
Change is propagated to all STM32F103RB/STM32F401RE based boards and
respective pinmux drivers

Add driver for CMSDK APB UART ports. The driver implements RX and TX
functionalities. Data transmission is implemented using polling and
interrupts. The driver default configuration for the port is to use
8bit data transmission, 1 stop bit, no parity control.
The driver exposes a public uart driver API and allows to register up
to five UART devices: from 'UART_0' to 'UART_4'. The driver performs
the required pinmux, the clock control configuration is left to the
platform.
The driver has been verified to work with the Hello World sample
application on a Beetle Board.

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 uart_k20 serial driver incorrectly assumed that all instances of the
UART peripheral are driven by the system clock, when actually some
instances are driven by the bus clock (which usually runs at half the
system clock). This caused incorrect baud rate calculations for UART
instances driven by the bus clock (UART2-4).

- QM_IRQ_* renamed too, mostly added _INT at the end;
- some isr functions were renamed to keep their names consistent;
- build for x86 needs to define QM_LAKEMONT, as QM_SENSOR was for ARC.

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.

PCI enumeration modifies pci_dev and port at driver initialization,
these objects move from config_info to driver_data in preparation for
config_info becoming const.
This driver shares a unified uart configuration structure with other
uart device drivers. The structure uses 'union' and the preprocessor
to customize the structure to the drivers specific requirement. There
appears to be no compelling reason why all the uart drivers should
share the same (customized) config_info structure. In order to
re-organize the structure for this driver to get config_info const, an
ns16550 specific config structure is defined and the driver switched
over from the generic uart_config.
