Revert "drm/i915/tgl/dsi: Gate the ddi clocks after pll mapping"

Browse Source 
This reverts commit 991d9557b0 ("drm/i915/tgl/dsi: Gate the ddi clocks
after pll mapping"). The Bspec was updated recently with the pll ungate
sequence similar to that of icl dsi enable sequence. Hence reverting.

Bspec: 49187
