x86/MCE/AMD: Carve out the MC4_MISC thresholding quirk

Browse source

The MC4_MISC thresholding quirk needs to be applied during S5 -> S0 and
S3 -> S0 state transitions, which follow different code paths. Carve it
out into a separate function and call it mce_amd_feature_init() where
the two code paths of the state transitions converge.

 [ bp: massage commit message and the carved out function. ]
