drm/amd/display: remove output_tf_change flag

Browse Source 
[ Upstream commit 41b1f9fcba62b06195e625bb88c1031102892439 ]

Remove this flag as the driver stopped managing it individually since
commit a4056c2a63 ("drm/amd/display: use HW hdr mult for brightness
boost"). After some back and forth it was reintroduced as a condition to
`set_output_transfer_func()` in [1]. Without direct management, this
flag only changes value when all surface update flags are set true on
UPDATE_TYPE_FULL with no output TF status meaning.

Fixes: bb622e0c00 ("drm/amd/display: program output tf when required") [1]
