Currently the device is powered down in the remove callback, however
all other clean up is done through devres. The problem here is the
MFD children are cleaned up through devres. As this happens after
the remove callback has run, this leads to the incorrect ordering
where the child remove functions run after the device has been powered
down. Put the power down into devres as well such that everything runs
in the expected order.

Use more forward declarations, move header guards to cover other
includes, and rely less on including headers through other headers.

The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface
(Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed
for portable applications. It provides a high dynamic range, stereo
DAC for headphone output, two integrated Class D amplifiers for
loudspeakers, and two ADCs for wired headset microphone input or
stereo line input. PDM inputs are provided for digital microphones.
The MFD component registers and initialises the device and provides
PM/system power management.
