drivers: i2c: mentor: move platform code into header files

At the moment we have two I2C stub drivers (for the Allwinner and the
Marvell platform), which #include the actual .c driver file.
Change this into the more usual design, by renaming and moving the stub
drivers into platform specific header files and including these from the
actual driver file. The platform specific include directories make sure
the driver picks up the right header automatically.

ARM platforms: Reintroduce coherent memory for BL1 and BL2

The patch d323af9 removed the support for coherent memory in BL1 and
BL2 for ARM platforms. But the CryptoCell SBROM integration depends
on use of coherent buffers for passing data from the AP CPU to the
CryptoCell. Hence this patch reintroduces support for coherent
memory in BL1 and BL2 if ARM_CRYPTOCELL_INTEG=1.

BL31: Fix warning about BL32 init function

The expected value for failure is 0, so the warning only has to be shown
in that case. This is the way the TSPD has done it since it was
introduced, and the way SPM and OP-TEE do it.

Trusty wrongly returns 0 on success.

In the case of TLK, the return value of tlkd_init() is passed from the
secure world in register X1 when calling the SMC TLK_ENTRY_DONE.

allwinner: sun50i_h6: initialise I2C just before powering down

Even though we initialise the platform part and the I2C controller
itself at boot time, we actually only access the bus on power down.
Meanwhile a rich OS might have configured the I2C pins differently or
even disabled the controller.
So repeat the platform setup and controller initialisation just before
we actually access the bus to power off the system. This is safe,
because at this point the rich OS should no longer be running.

allwinner: sun50i_h6: improve I2C setup

Drop the unnecessary check for the I2C pins being already configured as
I2C pins (we actually don't care).
Also avoid resetting *every* peripheral that is covered by the PRCM reset
controller, instead just clear the one line connected to the I2C controller.

Allow setting log level back to compile time value

When using the tf_log_set_max_level() function, one can dynamically
set the log level to a value smaller than then compile time specified
one, but not equal. This means that when the log level have been
lowered, it can't be reset to the previous value. This commit modifies
this function to allow setting the log level back to the compile time
value.

Fixes ARM-software/tf-issues#624
