x86/CPU/AMD: Add additional fixed RDSEED microcode revisions

commit e1a97a627cd01d73fac5dd054d8f3de601ef2781 upstream.

Microcode that resolves the RDSEED failure (SB-7055 [1]) has been released for
additional Zen5 models to linux-firmware [2]. Update the zen5_rdseed_microcode
array to cover these new models.
