[PATCH V2 1/1] OvmfPkg/RiscVVirt: Fix SCT memory allocation test case failure

["Sunil V L" <sunilvl@ventanamicro.com>]

Fix the UEFI memory range calculation by including the correct
stack memory range. Without this fix, SCT hangs in MemoryAllocation
test cases which call AllocateAddress().

Changes since V1:
	1) Fixed the inaccurate description regarding stack
	   growth (Thanks Andrei!)
	2) Simplified the fix.
