Description of changes

  1. ACPI for IPU7 MAX96724:
  • Added a configurable link frequency macro with a default fallback of 1 GHz when no value is provided.
  • Wired link-frequency properties to use the macro value.
  • Set ISX031 D3 MAX96724 platform instances to 1.25 GHz explicitly.
  1. DKMS and build version parsing:
  • Replaced fragile cut-based parsing with regex/sed-based extraction for kernel major/minor values.
  • Updated DKMS helper script parsing to correctly handle kernels with RT/vendor suffixes and fail fast on malformed versions.
