The ADC in i.mx93 is a total new ADC IP, add a driver to support
this ADC.
Currently, only support one shot normal conversion triggered by
software. For other mode, will add in future.

This driver supports 4 chips, by which only one (vcnl4010) handles
interrupts and has support for triggered buffer. The setup of these
functions is hardcoded for vcnl4010 inside the generic vcnl4000_probe,
and thus ignores the chip specific configuration structure where all
other chip specific functions are specified.
This complicates adding interrupt handler and triggered buffer support
to chips which may have support for it.
Add members for irq threads and iio_buffer_setup_ops to the generic
vcnl4000_chip_spec struct, so that instead of checking a chip specific
boolean irq support, we check for a chip specific triggered buffer
handler, and/or a chip specific irq thread handler.

Much like 807efb7102e8 ("thermal: qcom-spmi-adc-tm5: suppress

probe-deferral error on startup when a channel is not yet available:
[ 0.343136] qcom-spmi-adc-tm5 1c40000.spmi:pmic@0:adc-tm@3500: get dt data failed: -517
Suppress it by using dev_err_probe instead, which also takes care of
storing the message as reason for deferring.
