Lorenzo Bianconi 51a8b70762 iio: imu: st_lsm6dsx: add regmap API support
Introduce regmap API support to access to i2c/spi bus instead of
using a custom support. Set max bulk read to
(32 / SAMPLE_SIZE) * SAMPLE_SIZE since spi_write_then_read() used in
regmap_spi indicates that is the max buffer length to use in order to
avoid a kmalloc for each bus access.
Remove lock mutex since concurrency is already managed by regmap API

Say yes here to build support for STMicroelectronics LSM6DSx imu
sensor. Supported devices: lsm6ds3, lsm6ds3h, lsm6dsl, lsm6dsm
To compile this driver as a module, choose M here: the module
will be called st_lsm6dsx.
