In commit b24fca05751f ("OvmfPkg: introduce 4MB flash image (mainly) for
Windows HCK", 2017-04-29), I changed PcdFlashNvStorageFtwSpareSize to
264KB, in the then-new default 4MB build.
While PcdFlashNvStorageFtwSpareSize remains exactly half of the entire
non-volatile store (which is 528KB), 264KB isn't itself a power of two.
This triggers an assertion failure in AllocateAlignedRuntimePages() when
PlatformPei calls it from the ReserveEmuVariableNvStore() function,
passing PcdFlashNvStorageFtwSpareSize as the Alignment parameter:
> ASSERT MdePkg/Library/PeiMemoryAllocationLib/MemoryAllocationLib.c(196):
> (Alignment & (Alignment - 1)) == 0
Round up the alignment to the next power of two if necessary.
