Subject: [PATCH] ALSA: hdsp - Implement generic function to toggle settings

The driver contains multiple similar functions that change only a single
bit in the control register, only the bit position varies.

This patch implements a generic function to toggle a certain bit
position that will be used to replace the old code.
