All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

Some of COMPHY parameters depends on the hw connection between the SoC
and the PHY, which can vary on different boards e.g. due to different
wires length. Define the "porting layer" with some defaults
parameters. It ease updating static values which needs to be updated due
to board differences, which are now grouped in one place.

Example porting layer for a8k-db is under:
plat/marvell/a8k/a80x0/board/phy-porting-layer.h

If for some boards parameters are not defined (missing
phy-porting-layer.h), the default values are used
(drivers/marvell/comphy/phy-default-porting-layer.h)
and the following compilation warning is show:
"Using default comphy params - you may need to suit them to your board".

The common COMPHY driver code is extracted in order to be shared with
future COMPHY driver for A3700 SoC platforms

Use PF instead of PP post-fix, since it is referring to "Phase Final"
(only G3 related register had correct spelling for relevant bit).
