nvmem: Correct some typos in comments

Fixed some confusing typos that were currently identified with codespell,
the details are as follows:

-in the code comments:
drivers/nvmem/brcm_nvram.c:25: underlaying ==> underlying
drivers/nvmem/core.c:1250: alredy ==> already
drivers/nvmem/core.c:1268: alredy ==> already
drivers/nvmem/lpc18xx_otp.c:24: reseverd ==> reserved
drivers/nvmem/microchip-otpc.c:159: devide ==> divide
