nvmem: Add R-Car E-FUSE driver
R-Car Gen4 SoCs contain fuses indicating hardware support or hardware
(e.g. tuning) parameters. Add a driver to access the state of the
fuses. This supports two types of hardware fuse providers:
1. E-FUSE non-volatile memory accessible through the Pin Function
Controller on R-Car V3U and S4-8,
2. E-FUSE non-volatile memory accessible through OTP_MEM on R-Car V4H
and V4M.
The state of the cells can be read using the NVMEM framework, either
from kernel space (e.g. by the Renesas UFSHCD driver), or from
userspace.
