Based on testing branch of iio.git

IMPORTANT NOTE: There are already upstreamed fixes for this driver [1], [2] and
there is an upcoming one [3]. They will probably conflict with the the last
three commits PATCH [3-5/5]. The solution should be quite trivial with minor
changes in these 3 patches. When it is deemed necessary I can resubmit the
patches or help with resolving the issue:

Changes in v7:

PATCH [1/5]:
	- PATCH [5/9] of previous version
	- Moved comments to correct locations and dropped unnecessary casting.

PATCH [2/5]:
	- Used bmp580_nvmem_{read/write}_impl() functions for the read/write
	  operations and bmp580_nvmem_{read/write}() for applying the power
	  managent functions in order to keep correct order of mutex unlocking
	  and power management with the guard(mutex).

PATCH [4/5]:
	- Used ARRAY_SIZE(bmpxxx_channels) for the .num_channels variable in the
	  bmp280_chip_info struct in order to make code better and more
	  maintainable

PATCH [5/5]:
	- Adjusted changes for the addition of ARRAY_SIZE(bmpxxx_channels) in
	  the previous commit.
