intel: enable Gen4-Gen8 support — 56 pre-Gen9 device IDs, remove probe gate

Browse Source 
drivers/mod.rs: remove Gen8+ gate in is_supported_intel_generation()
  All pre-Gen9 IDs (I965G, ILK, SNB, IVB/HSW/BDW) now pass probe.
  Gen8 Broadwell/Cherryview uses DDI display engine (same as Gen9) —
  expected to work with current register paths.
  Gen4-Gen7 (I965G through Haswell) use FDI display engine which differs
  from DDI. They will probe successfully but display init uses DDI_BUF_CTL
  registers that don't exist on FDI hardware. Full FDI support is documented
  as future work.

info.rs: +56 entries covering all pre-Gen9 generations
  Gen4: 18 IDs (I965G, G33, Q33/Q35, GM965, G45, GM45, Pineview)
  Gen5: 2 IDs (Ironlake desktop/mobile)
  Gen6: 7 IDs (Sandy Bridge GT1/GT2 desktop/mobile)
  Gen7: 11 IDs (Ivy Bridge, Haswell ULT/ULX GT1/GT2/GT3)
  Gen8: 18 IDs (Broadwell ULT/ULX GT1/GT2/GT3, Cherryview GT1/GT2)
  Total: 56 new entries → info.rs now has 157 device IDs
