The Allwinner SoCs all have an ADC that can also act as a touchscreen
controller and a thermal sensor. This patch adds the ADC driver which is
based on the MFD for the same SoCs ADC.
This also registers the thermal adc channel in the iio map array so
iio_hwmon could use it without modifying the Device Tree. This registers
the driver in the thermal framework.
The thermal sensor requires the IP to be in touchscreen mode to return
correct values. Therefore, if the user is continuously reading the ADC
channel(s), the thermal framework in which the thermal sensor is
registered will switch the IP in touchscreen mode to get a temperature
value and requires a delay of 100ms (because of the mode switching),
then the ADC will switch back to ADC mode and requires also a delay of
100ms. If the ADC readings are critical to user and the SoC temperature
is not, this driver is capable of not registering the thermal sensor in
the thermal framework and thus, "quicken" the ADC readings.
This driver probes on three different platform_device_id to take into
account slight differences (registers bit and temperature computation)
between Allwinner SoCs ADCs.

Due to RST rework, the reference to i2c/trivial-devices was changed, but the
result is broken. However, let's just drop the whole reference, since it
doesn't make sense in the first place to reference this "global" file
for a single driver.

The camera code has an explicit cache flush operation
which is not portable. Now that vc04_services is using portable
DMA APIs that already do the cache flushing, explicit flushes
should no longer be needed.
The one call to __cpuc_flush_dcache_area has been removed.
Testing:
The offical V2 camera for the RPI was tested on a RPI 3
running in 32 bit mode(armhf). The cheese application
and ffmpeg was used to view and stream video from the
camera. Nothing new seems to be broken without the
cache flushing.

So fix up the include file references to be relative to make it obvious
