We are asked to reprogram PEG_BAND_GAP_DATA prior to enabling
hotplug detection on the g45 HDMI/DP ports. Currently we do said
reprogamming from the DP/HDMI connector initialization functions.
That code should be mostly platform agnostic so clearly not the
best place for this. Move the workaround to the place where we
actually enable HPD detection.

Hotplug setup for Xe2_LPD differs from Xe_LPD+ by the fact that the
extra programming for hotplug inversion and DDI HPD filter duration is
not necessary anymore. As mtp_hpd_irq_setup() is reasonably small,
prefer to fork it into a new function for Xe2_LPD instead of adding a
platform check.

Differently from previous version, Xe2_LPD groups all port AUX interrupt
bits into PICA interrupt registers.
While at it, drop some trailing newlines.

On TGP, the RTC (always running) was reduced from 3MHz to 32KHz.
As a result of this change, when HPD active going low pulse or HPD IRQ
is presented and the refclk (19.2MHz) is not toggling already toggling,
there is a 60 to 90us synchronization delay which effectively reduces
the duration of the IRQ pulse to less than the programmed 500us filter
value and the hot plug interrupt is NOT registered.
Solution was to Reduce SHPD_FILTER to 250us for ADL and above.
This solution was derived when the below patch was floated.

and after some internal discussion Ville's suggestion made sense.

Split (non-hotplug) display irq handling out of i915_irq.[ch] into
display/intel_display_irq.[ch].
v3:
- Preserve [I915_MAX_PIPES] harder (kernel test robot)
v2:
- Rebase
- Preserve [I915_MAX_PIPES] in functions (kernel test robot)

Split hotplug irq handling out of i915_irq.[ch] into
display/intel_hotplug_irq.[ch].
The line between the new intel_hotplug_irq.[ch] and the existing
intel_hotplug.[ch] needs further clarification, but the first step is to
move the stuff out of i915_irq.[ch].
