nvmem: add snvs_lpgpr driver
This is a driver for Low Power General Purpose Register (LPGPR) available on i.MX6 SoCs in Secure Non-Volatile Storage (SNVS) of this chip. It is a 32-bit read/write register located in the low power domain. Since LPGPR is located in the battery-backed power domain, LPGPR can be used by any application for retaining data during an SoC power-down mode.
