[PATCH v2 7/9] ASoC: ux500: Remove obsolete PRCMU QoS calls

[Linus Walleij <linusw@kernel.org>]

The DB8500 PRCMU QoS interface consists of unconditional inline stubs,
so the MSP calls and cached constraint state have no effect. Device
power and clocks are already represented by the regulator, power-domain
and common-clock frameworks.

Remove the dead calls and their private state instead of pretending to
change the APE operating point.
