ALSA: hda - Fix the cmd cache keys for amp verbs

upstream commit: fcad94a4c71c36a05f4d5c6dcb174534b4e0b136

Fix the key value generation for get/set amp verbs.  The upper bits of
the parameter have to be combined with the verb value to be unique for
each direction/index of amp access.

This fixes the resume problem on some hardwares like Macbook after
the channel mode is changed.
