ASoC: Fixes for v7.1

This round of fixes is mostly Sirini's Qualcomm cleanups that have been
in review for a while, we also have a couple of small fixes from Cássio.

drm/i915/psr: Add defininitions for INTEL_WA_REGISTER_CAPS DPCD register

EDP specification says:

"If either VSC SDP is unable to be transmitted 100 ns before the SU region,
the Source device may optionally transmit the VSC SDP during the prior
video scan line’s HBlank period There is a Intel specific drm dp register
currently containing bits related how TCON can support PSR2 with SDP on
prior line."

Unfortunately many panels are having problems in implementing this. So
there is a custom Intel specific DPCD register (INTEL_WA_REGISTER_CAPS) to
figure out if this is properly implemented on a panel or if panel doesn't
require that 100 ns delay before the SU region. Here are the definitions in
this custom DPCD address:

0 = Panel doesn't support SDP on prior line
1 = Panel supports SDP on prior line
2 = Panel doesn't have 100ns requirement
3 = Reserved

Add definitions for this new register and it's values into new header
intel_dpcd.h.

v2: add INTEL_DPCD_ prefix to definitions
