Introducing Raspberry Pi 4B model.
It contains new BCM2838 SoC, PCIE subsystem,
RNG200, Thermal sensor and Genet network controller.

It can work with recent linux kernels 6.x.x.
Two avocado tests was added to check that.

Unit tests has been made as read/write operations
via mailbox properties.

Genet integration test is under development.

Every single commit
1) builds without errors
2) passes regression tests
3) passes style check*
*the only exception is bcm2838-mbox-property-test.c file
containing heavy macros usage which cause a lot of
false-positives of checkpatch.pl.

I did my best to keep the commits less than 200 changes,
but had to make some of them a bit more in order to
keep their integrity.

This is v2 patchset with the most of v1 remarks fixed.
I named it as 'v3' because of mistakes while attempts to send v2 patchset.
Please remove all other v1 and v2 patchsets except the very first one.
