Subject: drm/i915/xe2lpd: Handle port AUX interrupts
Git-commit: 925163b4af66dcf18e0f0dcd2ceffd3b7e5965af
Patch-mainline: v6.7-rc1
References: jsc#PED-3527 jsc#PED-5475 jsc#PED-6068 jsc#PED-6070 jsc#PED-6116 jsc#PED-6120 jsc#PED-5065 jsc#PED-5477 jsc#PED-5511 jsc#PED-6041 jsc#PED-6069 jsc#PED-6071
Differently from previous version, Xe2_LPD groups all port AUX interrupt
bits into PICA interrupt registers.
While at it, drop some trailing newlines.
