intel: CRITICAL — wire all 30 dead modules + EOI interrupt fix

mod.rs: added pub mod declarations for all previously-dead modules
  PHY: mg_pll, dkl_phy, cx0_phy, snps_phy, edp_pll
  Power: rps_rc6, dmc_power, psr_full, guc_submission, alpm
  Display: dp_fec, dp_audio, hdmi_frl, hdmi_scrambler, dp_uhbr,
           dp_phy, vrr, dsc, display_irq, bandwidth, panel_fitter
  Platform: lspcon, tc_port
  GT: workarounds, gpu_reset
  Support: audio_eld, cdclk_tables, color_lmem, color_pipeline

handle_irq: fixed MSI-X EOI gap
  InterruptHandle::eoi() now called after process_irq()
  Lock held across IRQ processing to prevent early drop
  Prevents MSI-X vectors from firing only once

30 modules were never compiled — now all 65 source files participate
in compilation. Legacy issues in previously-uncompiled modules remain
and will be addressed separately.
