drm/i915: fix a read size argument

We want to read 3 bytes here, but because the parenthesis are in the
wrong place we instead read:

sizeof(intel_dp->edp_dpcd) == sizeof(intel_dp->edp_dpcd)

which is one byte.

Fixes: fe5a66f91c88 ("drm/i915: Read PSR caps/intermediate freqs/etc. only once on eDP")
