[PATCH, RFC 33/62] acpi: Remove __init from acpi table parsing functions

[Kirill A. Shutemov]

From: Alison Schofield <alison.schofield@xxxxxxxxx>

ACPI table parsing functions are useful outside of init time.

For example, the MKTME (Multi-Key Total Memory Encryption) key
service will evaluate the ACPI HMAT table when the first key
creation request occurs.  This will happen after init time.

Additionally, the table parsing functions can be used when
_HMA objects are evaluated at runtime. The _HMA object provides
a completely new HMAT, overriding the existing table. The table
parsing functions will come in handy for those events.
