Olivier Martin 01674afdad ArmPkg/ArmLib: Drain Write Buffer before DCache maintenance operations. 
Cache maintenance operations by Set/Way require that the Write Buffer
be drained before the cache is flushed.  Without that, the flush can
miss the most recent values written as they are still "pipelined".
That has unfortunate consequences, especially where code is being
copied to RAM.
The fix is to add DSB instructions before the affected operations.

Olivier Martin f6c5a29bb9 ArmPkg/ArmLib: Rationalise ArmReadMidr and cognate functions. 
The function ArmReadMidr has been recently added, but that functionality was
already present under other names such as Cp15IdCode and ArmMainIdCode.  This
change removes redundant code and moves the function to the Common library.
