soc/amd/picasso/include/southbridge: drop PM_CPU_CTRL define
Picasso and newer don't implement the P_CNT register to control the CPU
duty cycle and also trap the C state control IO addresses directly in
the CPU, so those won't reach the FCH. This register is unused in the
Picasso code and not even defined any more in the Cezanne PPR. The
Picasso PPR does define this register, but since it's useless and might
even just be a leftover form a pre-Zen CPU generation, drop the define.
