We only had a couple of array[] declarations, and changing them to just
use 'MAX()' instead of 'max()' fixes the issue.
This will allow us to simplify our min/max macros enormously, since they
can now unconditionally use temporary variables to avoid using the
argument values multiple times.

The HX83100A is a bit of an outlier in the Himax HX831xxx series of
touch controllers as it requires reading touch events through the AHB
interface of the MCU rather than providing a dedicated FIFO address like
the other chips do.
This patch implements the specific read function and introduces the
HX83100A chip with an appropriate i2c ID and DT compatible string.
The HX83100A doesn't have a straightforward way to do chip
identification, which is why it is not implemented in this patch.

Imagis IST3038 is another variant of Imagis IST3038 IC, which has
a different register interface from IST3038C (possibly firmware defined).
Unlike IST3038C/IST3032C, IST3038 has different registers for commands,
which means IST3038 doesn't use protocol B.
Similar to IST3032C and maybe the other variants, IST3038 has touch keys
support, which provides KEY_APPSELECT and KEY_BACK.
Add support for IST3038 with touch keys.

It is preferred to use sizeof(*pointer) instead of sizeof(type)
due to the type of the variable can change and one needs not
change the former (unlike the latter).
The refactoring is mostly trivial except for "usbtouchscreen.c"
file. Here, in the "mtouch_alloc" and "nexio_alloc" functions,
it is necessary to use a variable with a predefined type instead
of the "usbtouch->priv" variable (void * type). This way, the
"sizeof" operator can now know the correct size. Moreover, we
need to set the "usbtouch->priv" pointer after the memory
allocation since now the "kmalloc" return value is not assigned
directly.
This patch has no effect on runtime behavior.

When support for Silead touchscreens was orginal added some touchscreens
with older firmware versions only supported 5 fingers and this was made
the default requiring the setting of a "silead,max-fingers=10" uint32
device-property for all touchscreen models which do support 10 fingers.
There are very few models with the old 5 finger fw, so in practice the
setting of the "silead,max-fingers=10" is boilerplate which needs to
be copy and pasted to every touchscreen config.
Reporting that 10 fingers are supported on devices which only support
5 fingers doesn't cause any problems for userspace in practice, since
at max 4 finger gestures are supported anyways. Drop the max_fingers
configuration and simply always assume 10 fingers.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While add it, also remove commas after the sentinel entries.

Instead of manually extracting certain bits from registers with binary
ANDs and shifts, the FIELD_GET macro can be used. With this in mind, the
*_SHIFT macros can be dropped.

IST3032C is a touchscreen chip used for instance in the
samsung,coreprimevelte smartphone, with which this was tested. Add the
chip specific information to the driver.

Imagis IST3038B is another variant of Imagis IST3038 IC, which has
a different register interface from IST3038C (possibly firmware defined).
This should also work for IST3044B (though untested), however other
variants using this interface/protocol(IST3026, IST3032, IST3026B,
IST3032B) have a different format for coordinates, and they'd need
additional effort to be supported by this driver.
