drm/i915/alpm: ALPM disable fixes
commit eb4a7139e97374f42b7242cc754e77f1623fbcd5 upstream.
PORT_ALPM_CTL is supposed to be written only before link training. Remove
writing it from ALPM disable.
Also clearing ALPM_CTL_ALPM_AUX_LESS_ENABLE and is not about disabling ALPM
but switching to AUX-Wake ALPM. Stop touching this bit on ALPM disable.
Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/7153
Fixes: 1ccbf135862b ("drm/i915/psr: Enable ALPM on source side for eDP Panel replay")
