drm/amd/display: dispatch compressed FRL cap check inside dml1_frl_cap_chk_inter
[why]
DSC over HDMI FRL (e.g. 4k144) was pruned by DML mode support
because the compressed FRL cap check was never reached.
dml32_TruncToValidBPP() validates the FRL output by calling
dml1_frl_cap_chk_inter() directly. The compressed-vs-uncompressed
dispatch (if params->compressed -> dml1_frl_cap_chk_compressed()) had
been moved up into the top-level dml1_frl_cap_chk() wrapper, leaving
dml1_frl_cap_chk_inter() as uncompressed-only. As a result a DSC stream
routed through TruncToValidBPP was validated against the full
uncompressed bandwidth, failed the cap check, and the mode was pruned
(vlevel == num_states).
[how]
Move the compressed dispatch back into dml1_frl_cap_chk_inter() so every
caller of _inter() (including TruncToValidBPP) honours params->compressed.
This matches the internal DAL tree.
