Vladimir Olovyannikov c4709260f6 EmbeddedPkg/CoherentDmaLib: Add missing checks to DmaMap
UEFI Sct validates Dma mapping. For CoherentDmaLib it always failed
because there were no required checks present in DmaMap.

Vladimir Olovyannikov c783da6599 EmbeddedPkg/CoherentDmaLib: Fix typo in DmaAlignedBuffer
The only valid memory types for DmaAlignedBuffer should be
EfiBootServicesData and EfiRuntimeServicesData. However due to the typo,
there is no way to allocate runtime pages, and INVALID_PARAMETER is
always returned. Fix the typo.

Ard Biesheuvel 7385d2543e EmbeddedPkg: rename NullDmaLib to CoherentDmaLib
The name NullDmaLib suggests that this library is a placeholder that
only exists to fulfil formal dependencies on the DmaLib library class
without providing an actual implementation. This is not the case, though:
NullDmaLib does implement DmaLib fully, but doing so simply requires very
little effort on a cache coherent platform. So let's rename it to
CoherentDmaLib instead.
