The global variable "kvx_serial" has been renamed to "kvx_mppa_id".
Do the same with the function name that sets this global variable.

When calling nvmem_cell_get_and_read the resulting memory must be freed.

Add the magic variable "kvx.board_sn" that will reflect the board serial
number stored in OTP.
