eDP1.5 adds some more bits into DP_RECEIVER_ALPM_CAP and
DP_RECEIVER_ALPM_CONFIG registers. Add definitions for these.

This bit seems to be derived from DP 2.1.
As per eDP1.5: Only bits [1 and 0] are eDP-specific. The register’s
other bits are defined in DP Standard.
In any case, patch looks good to me.
