Add support for Imagis touchscreens, used on various mobile
devices such as Samsung Galaxy J5 (2015), J3 (2015), J5 (2016).

v2: rebase on top of the correct tree
v3:
- prefix all defines as IST3038C
- use two tabs for all defines
- add missing <linux/regulator/consumer.h> header
- drop ADDR_LEN and DATA_LEN defines; use sizeof(reg_be) instead
- use __be32 type for reg_be
- add a comment about i2c read not being successful on first try
- use "ret" instead of "res" in read_reg function
- don't use the internal __cpu_to_be32 function, use cpu_to_be32 instead
- use "error" instead of "ret" in interrupt handler
- pass the slot state directly, without ternary operator
- drop the dev_err in init_input_dev function
- reorder the functions in _probe so that the chipid command is read as fast 
as possible
- don't use imagis_start in probe
- initialize the irq after the chip is powered
- save the return value in imagis_resume
- drop WIDTH_MAJOR since only TOUCH_MAJOR is reported
- the "chip detected" message is now dev_dbg
- reorder headers so they are in alphabetic order
- use GENMASK to generate masks for getting the X and Y coordinates and touch area
- drop *_pressure from device tree bindings since the driver doesn't
support reporting pressure
- fix the typo with i2c address in device treee bindings (48 instead of 50)
- add IRQF_NO_AUTOEN flag to avoid unbalanced irq enable
