nvmem: imx-ocotp: Add i.MX8MM support
This patch adds support to burn the fuses on the i.MX8MM. https://www.nxp.com/webapp/Download?colCode=IMX8MMRM The i.MX8MM is similar to i.MX6 processors in terms of addressing and clock setup. The documentation specifies 60 discreet OTP registers but, the fusemap address space encompasses up to 256 registers. We map the entire putative 256 OTP registers.
