The following commit:
commit 2bdd045e3a30 ("drm/i915/psr: Check if VBT says PSR can be enabled.")
added some code with no usable functionality. Regardless of how the psr
default is set up in the BDB_DRIVER_FEATURES section, if the enable_psr
module parameter isn't specified it defaults to 0.
Remove this dead code, simplify the way that enable_psr is handled and
update the module parameter string to match the actual functionality.
