Hello build bot (Jenkins), Jason Glenesk, Raul Rangel, Marshall Dawson, Paul Menzel,

soc/amd/picasso: remove warm reset flag code

Since the MCA(X) registers have defined values on the cold boot path,
the is_warm_reset check can be dropped. Also the warm reset bit in the
NCP_ERR register doesn't behave as the PPR [1] suggested; no matter if
something was written to the register or the machine went through a warm
reset cycle, the NCP_WARM_BOOT bit never got set.

[1] checked with PPR for AMD Family 17h Models 11h,18h B1 (RV,PCO)
#55570 Rev 3.15
