iio: amplifiers: ada4250: use DMA-safe memory for regmap_bulk_read()
Use DMA-safe memory instead of stack-allocated memory for the call to
regmap_bulk_read() in the ada4250_init() function as this could be used
directly by a SPI controller.
Also remove unnecessary use of get_unaligned_le16() and explicitly
include linux/types.h e.g. for __le16 while we are fixing this up.
Note this is DMA issue does not appear to be an actual bug due to
internals of the regmap SPI implementation. However, for IIO we are
following guidance that we should not make that assumption.
