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.

The MemEncryptSevClearMmioPageEncMask() helper can be used for clearing
the memory encryption mask for the Mmio region.
The MemEncryptSevClearMmioPageEncMask() is a simplified version of
MemEncryptSevClearPageEncMask() -- it does not flush the caches after
clearing the page encryption mask.

Update the MemEncryptSevLib library to include an interface that can
report the encryption state on a range of memory. The values will
represent the range as being unencrypted, encrypted, a mix of unencrypted
and encrypted, and error (e.g. ranges that aren't mapped).

The declaration and the definition(s) of the function should have
identical leading comments and/or identical parameter lists. Replace any
leftover "clear" references to the C-bit with "set" references. Also
remove any excess space in the comment block, and unindent the trailing
"**/" if necessary. Correct several parameter references.

this. Rewrap all files to 79 columns.

Add Secure Encrypted Virtualization (SEV) helper library.
The library provides the routines to:
- set or clear memory encryption bit for a given memory region.
- query whether SEV is enabled.
