Lorenzo Bianconi 91a6b841a5 iio: imu: st_lsm6dsx: pre-allocate read buffer at bootstrap 
Allocate device read buffer at bootstrap and do not put it on the stack
since it is pretty big (~200B) and its size will increase adding support
to device hw timestamp.
Moreover this patch fixes following sparse warnings:
drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_buffer.c:250:17: warning: Variable length
array is used.
drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_buffer.c:283:55: error: cannot size
expression
