[PATCH 1/2] nvmem: imx: assign nvmem_cell_info::raw_len

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().

Fixes: 4327479e559c ("nvmem: core: verify cell's raw_len")

Tested on i.MX6ULL, but I assume that this is also required for 
imx-ocotp-ele.c (i.MX93).
