platform/x86: intel_pmc_ipc: Do not create iTCO watchdog when WDAT table exists
ACPI WDAT table is the preferred way to use hardware watchdog over the
native iTCO_wdt. Windows only uses this table for its hardware watchdog
implementation so we should be relatively safe to trust it has been
validated by OEMs.
Prevent iTCO watchdog creation if we detect that there is an ACPI WDAT
table.
