[PATCH V5 2/3] x86/tdx: Tidy reset_pamt functions

[Adrian Hunter]

tdx_quirk_reset_paddr() was renamed to reflect that, in fact, the clearing
is necessary only for hardware with a certain quirk.  That is dealt with in
a subsequent patch.

Rename reset_pamt functions to contain "quirk" to reflect the new
functionality, and remove the now misleading comment.
