OvmfPkg/BaseMemEncryptSevLib: remove Flush parameter
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275
The Flush parameter is used to provide a hint whether the specified range
is Mmio address. Now that we have a dedicated helper to clear the
memory encryption mask for the Mmio address range, its safe to remove the
Flush parameter from MemEncryptSev{Set,Clear}PageEncMask().
Since the address specified in the MemEncryptSev{Set,Clear}PageEncMask()
points to a system RAM, thus a cache flush is required during the
encryption mask update.
