drm/i915/display: Write PHY_CMN1_CONTROL only when using AUXLess ALPM
We are seeing "dmesg-warn/abort - *ERROR* PHY * failed after 3 retries"
since we started configuring LFPS sending. According to Bspec Configuring
LFPS sending is needed only when using AUXLess ALPM. This patch avoids
these failures by configuring LFPS sending only when using AUXLess ALPM.
Bspec: 68849
Fixes: 9dc619680de4 ("drm/i915/display: Add function to configure LFPS sending")
