- use sysfs_emit_at() instead of sprintf()

v4 -> v5:
- break up the changes in three patches
- replace error_ret labels by simple returns
- use spi_w8r16be() for be16 reads
- use guard(mutex) for handling mutex lock

v3 -> v4:
- clean the code and remove redundant operations

v2 -> v3:
- replace usages of internal read data helpers by spi helpers

v1 -> v2:
- simplify the return of the internal read data function
