soc/amd/picasso/acpi: don't announce unimplemented duty cycle control

Picasso neither has the corresponding P_CNT register implemented nor
writes a _PTC ACPI object that would specify the P_CNT register. The
Picasso UEFI reference code also sets the duty_width FADT entry to 0.
This also aligns the Picasso code with the Cezanne code in this regard.
