In edk2-platforms it is expected to provide a separation between
SoC and boards files in 'Silicon' and 'Platform' directories
accordingly.
This patch aligns Marvell code to this requirement with no functional
changes in the actual source files, unless required due to modified
paths. Change the supported board's files names to proper Armada70x0Db.
Also rename 'Armada' directory to 'Armada7k8k' in order to properly
refer to the SoC family and prevent confusion in future, when
adding new Armada machines. On the occasion add ARM copyright,
which was wrongly missing in the dsc.inc file.

During each transaction start, clearing the I2C_CONTROL_FLAG
was surrounded by 3 uncoditional stalls. This was not necessary,
so replace them with one busy-wait loop, whose polling
count could be also safely reduced.
Above improvements result in faster transfer initialization
and allow to reduce the I2C bus occupation.

In MvI2cStartRequest the status was assigned to the variable
without dereferencing a pointer. Fix it.

Although the I2C transaction routines were prepared to
return their status, they were never used. This could
cause bus lock-up e.g. in case of failing to send a
slave address, the data transfer was attempted to be
continued anyway.
This patch fixes faulty behavior by checking transaction
status and stopping it immediately, once the fail
is detected. On the occasion fix style around modified
functions calls.

This patch introduces I2c description, using the new structures
and template in MvHwDescLib. This change enables more flexible
addition of multiple I2c controllers and also allows for
removal of string PCD parsing. Update Armada 70x0 DB description
and PortingGuide accordingly.
