Some systems use older firmware which does not support newer commands
which are used to enable external boost. For those systems, we can
workaround this by writing the registers directly.
We can use the firmware version, stored inside cs_dsp, to determine
whether or not the command is supported.
To achieve this, it requires a cleanup in the api, to pass the cs_dsp
struct into the function.
We can also remove the redundant boolean firmware_running from the HDA
driver, and use the equivalent state inside cs_dsp.
This chain is based on Mark's branch, since the api change was made to
the function in sound/soc/codecs/cs35l41-lib.c.
