Fix pre-existing compilation errors in modules that were present as
source files but not declared in mod.rs:
- audio_eld: cast u16 copy_len to usize for slice indexing
- dp_fec, dp_uhbr, edp_pll, gpu_reset, hdmi_frl, lspcon:
DriverError::Initialization now takes String, add .to_string()
- dsc: add missing import
- guc_submission: DriverError::Buffer now takes String
- vrr: cast VRR_MAX/MIN_FRAME_TIME constants to usize
- rps_rc6: change freq_table() return to &'static to avoid
borrow checker conflict with self mutation
All 12 modules now compile with zero errors.
