Add initial support for ROHM/Kionix kx022a accelerometer

About the HW:
KX022A accelerometer is a sensor which:
	- supports G-ranges of (+/-) 2, 4, 8, and 16G
	- can be connected to I2C or SPI
	- has internal HW FIFO buffer
	- supports various ODRs (output data rates)
	- support detecting special events like double tap or motion
	- can be configured to wake-up system when events are detected.

About the series:

This series adds support for only getting the accelerometer data and
configuring the G-range / ODR via IIO. Motion detection or double-tap
detection are not supported by the series. The other quite important but
still missing piece is the runtime PM. Nevertheless, the driver should be
usable and brings the basic support for getting accelerometer data.

Changelog v4: (More detailed log in individual patches)
	- KX022A: mostly styling/print fixes.
	- KX022A: fix return value from IRQ thread handler.

Changelog v3: (More detailed log in individual patches)
	- dt-bindings: fixed as suggested by Krzysztof
	- KX022A: multiple fixes as suggested by Andy
		- Fair to mention that couple of suggested changes are
		  not done (Some styling, boilerplate text in KConfig)
		  as there has been no consensus whether the suggested
		  changes improve situation. Ultimately the decision
		  whether these changes are mandatory lay on the
		  shoulders of the maintainers... Sorry for that.
	- Enable the FIFO without module param now that the "FIFO stuck"
	  issue can be prevented.
	- Fix potential race with time-stamp calculation when user-space
	  invokes the fifo flush.
	- Drop the already merged regulator patches.

Changelog v2: (More detailed log in individual patches)
	- dt-bindings: fixed as suggested by Krzysztof
	- dt-bindings: support both INT1 and INT2
	- KX022A: multiple fixes as suggested by Jonathan
	- fixed SPI driver after some testing
