From: Gustavo Sousa <gustavo.so...@intel.com>
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.
v2: Add extra bspec reference and fix missing else (Matt Roper)
