[SRU][O/P:linux][PATCH 0/5] Fix ARL-U/H suspend issues

[Thibault Ferrante]

BugLink: https://bugs.launchpad.net/bugs/2112469

[ Impact ]

 * Multiple issues are noticed when validating Arrow Lake hardware after suspend.
  - An ethernet interface cannot be up after suspend - LP: #2111232
  - Found Network Controller configurations differences while running suspend stress tests - LP: #2110284
  - Found DRM Device configurations differences while running suspend stress test - LP: #2110284

[ Fix ]

Fix has been pointed out by intel by integrating https://patchwork.kernel.org/project/linux-pm/patch/20250207225615.401235-7-xi.pardee@linux.intel.com/

It has been integrated in 6.15 :
- bd820906ea9d platform/x86/intel/pmc: Add Arrow Lake U/H support to intel_pmc_core driver

4 other commits has been picked in the way but are only refactoring and target only this specific driver.

[ Test Plan ]

 * Use targeted hardware to go into S3 and check for all network interfaces working.

[ Where problems could occur ]

 * Regression in other intel hardware suspend management.

[ Other Info ]

 * This is submitted for oracular even if EOL is soon as the validation/certification is currently happening on this kernel.
