nvmem: add new NXP QorIQ eFuse driver
Add SFP (Security Fuse Processor) read support for NXP (Freescale)
QorIQ series SOC's.
This patch adds support for the T1023 SOC using the SFP offset from
the existing T1023 device tree. In theory this should also work for
T1024, T1014 and T1013 which uses the same SFP base offset.
