[PATCH] nvmem: imx: assign nvmem_cell_info::raw_len

[PATCH] nvmem: imx: assign nvmem_cell_info::raw_len

[Fabio Estevam]

From: Christian Eggers <ceggers@arri.de>

Avoid getting error messages at startup like the following on i.MX6ULL:

nvmem imx-ocotp0: cell mac-addr raw len 6 unaligned to nvmem word size 4
nvmem imx-ocotp0: cell mac-addr raw len 6 unaligned to nvmem word size 4

This shouldn't cause any functional change as this alignment would
otherwise be done in nvmem_cell_info_to_nvmem_cell_entry_nodup().
