Subject: [PATCH 5.19 15/38] drm/i915/vdsc: Set VDSC PIC_HEIGHT before using for DP DSC

From: Ankit Nautiyal <ankit.k.nautiyal@...el.com>

[ Upstream commit 0785691f5711a8f210bb15a5177c2999ebd3702e ]

Currently, pic_height of vdsc_cfg structure is being used to calculate
slice_height, before it is set for DP.

So taking out the lines to set pic_height from the helper
intel_dp_dsc_compute_params() to individual encoders, and setting
pic_height, before it is used to calculate slice_height for DP.

Fixes: 5a6d866f8e1b ("drm/i915: Get slice height before computing rc params")
