spmi: Debug-fs support for SPMI
Add user space interface to the SPMI kernel framework that enables
master-read and master-write transactions.
Each SPMI controller is represented as a file under the root directory
of SPMI debug-fs. For each controller, 'address', 'count', and 'data'
files are added. The user may configure the transaction via the
respective files and invoke a master read transaction by reading from
the 'data' file, and a master write transaction by writing a string of
decimal or hexadecimal byte size values to the 'data' file.
