Subject: [PATCH AUTOSEL 6.6 22/39] platform/x86/amd/pmc: Move keyboard wakeup disablement detection to pmc-quirks

From: Mario Limonciello <mario.limonciello@....com>

[ Upstream commit b614a4bd73efeddc2b20d9e6deb6c2710373802b ]

Other platforms may need to disable keyboard wakeup besides Cezanne,
so move the detection into amd_pmc_quirks_init() where it may be applied
to multiple platforms.
