drm/amd/display: Enable dpia in dmub only for DCN31 B0
[Why] DMUB binary is common for both A0 and B0. Hence, driver should notify FW about the support for DPIA in B0. [How] Added dpia_supported bit in dmub_fw_boot_options and will be set only for B0. Assign dpia_supported to true before dm_dmub_hw_init in B0 case. v2: fix build without CONFIG_DRM_AMD_DC_DCN (Alex) Signed-off-by: Jude Shih <shenshih@amd.com> Reviewed-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
