Merge branch 'rx-software-timestamp-for-all'

Gal Pressman says:

====================
RX software timestamp for all

All devices support SOF_TIMESTAMPING_RX_SOFTWARE by virtue of
net_timestamp_check() being called in the device independent code.
Following Willem's suggestion [1], make it so drivers do not have to
handle SOF_TIMESTAMPING_RX_SOFTWARE and SOF_TIMESTAMPING_SOFTWARE, nor
setting of the PHC index to -1.

All drivers will now report RX software timestamp as supported.
The series is limited to 15 patches, I will submit other drivers in
subsequent submissions.
