platform/x86/amd/pmc: Only run IRQ1 firmware version check on Cezanne

Browse Source 
[ Upstream commit 2d53c0ab61 ]

amd_pmc_wa_czn_irq1() only runs on Cezanne platforms currently but
may be extended to other platforms in the future.  Rename the function
and only check platform firmware version when it's called for a Cezanne
based platform.
