drm/i915/psr: Disable PSR2 SU Region ET if enable_psr module parameter is set
Currently PSR2 SU Region Early Transport is enabled by default on Lunarlake
if panel supports it despite enable_psr module parameter value. This patch
makes it possible for user to limit used PSR mode and prevent SU Region
Early Transport by setting enable_psr as 2. With default (-1) PSR2 SU
Region Early Transport is allowed.
v2: fix/improve commit desciption
