platform/x86/amd/pmf: Refactor repetitive BIOS output handling

Browse source

Replace repetitive switch-case statements for PMF_POLICY_BIOS_OUTPUT_*
with a helper function and consolidated case handling. This reduces code
duplication and improves maintainability.

The 10 BIOS output policies (PMF_POLICY_BIOS_OUTPUT_1 through
PMF_POLICY_BIOS_OUTPUT_10) previously each had individual case statements
with identical logic. This patch introduces
amd_pmf_get_bios_output_idx() to map policy values to array indices,
consolidating the handling into a single case block with fallthrough.
Also, add a new function amd_pmf_update_bios_output() to simplify the code
handling.

This approach handles non-sequential policy enum values gracefully and
makes future additions easier to implement.

No functional changes.
