[PATCH v4 3/4] platform/x86/amd/hsmp: Add ACPI client support for Family 1Ah

[Muralidhara M K <muralidhara.mk@amd.com>]

The ACPI HSMP device (HID AMDI0097) on the Family 1Ah client platforms
(Models 80h-8Fh and E0h-E3h) describes its mailbox the same way server
platforms already do, via _CRS/_DSD, so hsmp_parse_acpi_table() and
hsmp_get_uid() need no client-specific handling.

Client platforms don't report a server protocol version, so also gate
the metric table DRAM base lookup on is_client_platform() alongside
the existing proto_ver check, so client platforms get their metric
table base initialized too.
