* Fixes#5256.
* Specify an initial baud rate to use during startup.
After the PL011 code refactor in
0f42153959, an initial baud rate
is required. arm_pl011_first_open is called from boot_card and
will fail without a baud rate specified. This can cause certain
future uses of /dev/console, such as opening a shell, to fail.
- Refactor the pl011 driver to be extensible.
- Add IRQ support and baudrate configuration support for pl011 driver.
- Modify related BSP.
- Add doxygen comments for arm-pl011.
Close#5026

This patch adds driver for Mini UART present in Raspberry Pi 3
and above, this UART is currently used as the primary UART in
these models.
The Mini UART is similar to ns16550, this driver is built
upon libchip/ns16550.
Use RTEMS_SYSINIT_ORDER_LAST_BUT_5 instead of RTEMS_SYSINIT_ORDER_LAST
to allow applications and support functions to place system
initialization handlers behind the standard handlers.
Update #3838.
