drm/xe: Only request PCODE_WRITE_MIN_FREQ_TABLE on LLC platforms
PCODE_WRITE_MIN_FREQ_TABLE is only applicable to platforms with an LLC.
Change the discrete GPU check to an LLC check instead; this take care of
skipping not only the discrete platforms, but also integrated platforms
like MTL that do not have an LLC.
Fixes MTL dmesg error:
xe 0000:00:02.0: [drm] *ERROR* PCODE Mailbox failed: 1 Illegal Command
