[SRU][OEM-B-OSP1][PATCH RESEND 1/1] Revert "UBUNTU: SAUCE: i915: set disable_power_well=0 for icl temporarily"

[Hui Wang]

BugLink: https://bugs.launchpad.net/bugs/1839950

This reverts commit 63361ff9a85dca6bb493638e1fffcff38b755702.

After applying the fix of #1847192, we can't reproduce the hdmi audio
issue anymore on the icl laptop even without disable_power_well=0,
and disable_power_well=0 will prevent the CPU from entering PC10 power
state, let us revert this patch.
