drm/i915/display: Get bigjoiner config before dsc config during readout

Currently we get bigjoiner config after the dsc get config, during HW
readout.
Since dsc_get_config now uses bigjoiner flags/pipes to compute DSC PPS
parameter pic_width, this results in a state mismatch when Bigjoiner
and DSC are used together.

So call get bigjoiner config before calling dsc get config function.
