Remove dependency between pll (hppll, lppll) and headset power
mode (low-power, high-performance), as headset power mode can
be used with any pll.

Acked-by: Mark Brown <redacted>

but...

A new control is created to allow headset power mode configuration
from userspace. Changing headset power mode during earpiece related
usecases is not allowed as earpiece requires HS DAC in HP mode.

Might be nicer to allow the user to set the control given that you'll
just ignore the configured value anyway if it's not usable right now.
