This cleanups 2 things:
1) The first time we loop over the crtc-s, to compare framebuffers, fb1 may
get set to NULL by the fb1 = CRTC_FB(crtci); statement and then we call
to_vbox_framebuffer() on it. The result of this call is only used for
an address comparison, so we don't end up dereferencing the bad pointer,
but still it is better to not do this.
2) Since we already figure out the first crtc with a fb in the first loop
and store that in fb1, there is no need to loop over the crtc-s again just
to find the first crtc with a fb again.

The correct way to handle errors returned by regualtor_get() and friends is
to propagate the error since that means that an regulator was specified,
but something went wrong when requesting it.
For handling optional regulators, e.g. when the device has an internal
vref, regulator_get_optional() should be used to avoid getting the dummy
regulator that the regulator core otherwise provides.

Until now the "channel" number is identical to how the channel is
identified inside the (FIFO) registers. In our case we have eight
channels and the hardware also has eight inputs.
However, there are two special inputs:
- channel 6 can select between the SAR_ADC_CH6 pad and the chip's
internal temperature sensor
- channel 7 can select between SAR_ADC_CH7 and VSS, VDD / 4, VDD / 2,
VDD * 3 / 4 and VDD.
When programming the registers to read for example the temperature
sensor we have to select FIFO channel 6, set the correct bit which muxes
channel 6 to the temperature sensor and then start the ADC measurement
for channel 6 as usual.
When we add support for the temperature sensor the driver has to know
about that it has to use FIFO channel 6 to measure using the chip's
internal temperature sensor. However, in that case the iio_chan_spec
channel will not be 6 because this is already used for the SAR_ADC_CH6
pad input. Thus we use iio_chan_spec's address field to store the FIFO
channel number for each channel.

In the future we may support two different channel sets:
- one which includes the voltage pads and the temperature sensor output
(for Meson8, Meson8b and Meson8m2)
- one which only includes the voltage pads (GXBB, GXL, GXM and AXG)
Channel 7 has a special function on all of these platforms. However,
since we will have different channel array definitions we want our code
to always use whatever channels struct iio_dev uses.
No functional changes for now. This is the preparation for adding
temperature sensor support to this driver.

When channels are registered, the hardware channel number is not the
actual iio channel number.
This is because the driver is probed with a certain number of accessible
channels. Some pins are routed and some not, depending on the description of
the board in the DT.
Because of that, channels 0,1,2,3 can correspond to hardware channels
2,3,4,5 for example.
In the buffered triggered case, we need to do the translation accordingly.
Fixed the channel number to stop reading the wrong channel.

When doing simple conversions, the driver did not acknowledge the DRDY irq.
If this irq status is not acked, it will be left pending, and as soon as a
trigger is enabled, the irq handler will be called, it doesn't know why
this status has occurred because no channel is pending, and then it will go
int a irq loop and board will hang.
To avoid this situation, read the LCDR after a raw conversion is done.

Commit 053ffe3c8c ("iio: adc: meson-saradc: squash and share the
common adc platform data") put all the data which is needed at runtime
from struct meson_sar_adc_data to a new struct meson_sar_adc_param so
we can re-use the platform specific configuration without having to
duplicate everything just to change the name.
The only place where struct meson_sar_adc_data is now needed is the
_probe function which has to pass the name to the iio_dev. All other
functions only need access to struct meson_sar_adc_param. This means we
can simplify struct meson_sar_adc_priv.
The goal of this patch is to make the code a bit easier to read since
this removes one level of nesting. No functional changes intended.

This define is of no use because the driver is avoiding shifting bits
by itself but using FIELD_GET/FIELD_PREP (which are using bit masks)
instead. There is already a MESON_SAR_ADC_DELTA_10_TS_C_MASK bit mask so
MESON_SAR_ADC_DELTA_10_TS_C_SHIFT was redundant.
