Charles Keepax 06bdf385f6 ASoC: cs35l35: Allow user to configure IMON SCALE
On the chip the IMON signal is a full 24-bits however normally only
some of the bits will be sent over the bus. The chip provides a field
to select which bits of the IMON will be sent back, this is the only
feedback signal that has this feature.

Add an additional entry to the cirrus,imon device tree property to
allow the IMON scale parameter to be passed.

Charles Keepax 77b329d194 ASoC: cs35l35: Correct handling of PDN_DONE with external boost
When using an external boost supply the PDN_DONE bit is not set, update
the handling in this case to use to use an appropriate fixed delay.

Charles Keepax 8d45f2d238 ASoC: cs35l35: Add for configuring drive mode in unused slots
Add support for setting how the I2S pins are driven in unused slots,
currently the chip will just use the default of drive 0, however this
causes issues when multiple devices are attached to the same bus.
