drm/i915/display/psr: Set partial frame enable when forcing full frame fetch

Following up what was done in commit 804f46885317 ("drm/i915/psr: Set
"SF Partial Frame Enable" also on full update") and also setting
partial frame enable when psr_force_hw_tracking_exit() is called.

Also as PSR2_MAN_TRK_CTL is a double buffered registers do a RMW
is not a good idea so here also setting the man_trk_ctl_enable_bit()
that is required in TGL and only doing a register write.

v2:
- not doing a rmw

v3:
- removing the inline from functions that return PSR2_MAN_TRK_CTL
bits
