refactor(rpi): split out console registration logic

Detection of the UART in use and GPIO code only apply to RPi 3 and 4.

RPi 5 has a dedicated PL011 debug port.

refactor(rpi): move more platform-specific code into common

In preparation for RPi 5 support, which will reuse most of the RPi 4
logic except for DTB patching.

The plat_helpers.S file was almost identical between its RPi3 and RPi4
versions. Unify the two files, moving it into the common/ directory.

rpi: move plat_helpers.S to common

The plat_helpers.S file was almost identical between its RPi3 and RPi4
versions. Unify the two files, moving it into the common/ directory.

This adds a plat_rpi_get_model() function, which can be used to trigger
RPi4 specific action, detected at runtime. We use that to do the RPi4
specific L2 cache initialisation.

rpi3: console: Use same "clock-less" setup scheme as RPi4

In the wake of the upcoming unification of the console setup code
between RPi3 and RPi4, extend the "clock-less" setup scheme to the
RPi3. This avoid programming any clocks or baud rate registers,
which makes the port more robust against GPU firmware changes.

rpi3: Allow runtime determination of UART base clock rate

At the moment the UART input clock rate is hard coded at compile time.
This works as long as the GPU firmware always sets up the same rate,
which does not seem to be true for the Raspberry Pi 4.

In preparation for being able to change this at runtime, add a base
clock parameter to the console setup function. This is still hardcoded
for the Raspberry Pi 3.
