drm/i915/display: Fix handling of enable_psr parameter

Commit 3cf050762534 ("drm/i915/bios: Split VBT data into per-panel vs.
global parts") cause PSR to be disabled when enable_psr has the
default value and there is at least one DP port that do not supports
PSR.

That was happening because intel_psr_init() is called for every DP
port and then enable_psr is globaly set to 0 based on the PSR support
of the DP port.

Here dropping the enable_psr overwritten and using the VBT PSR value
when enable_psr is set as default.
