nvmem: split out the reg_read/write() callbacks out of struct nvmem_device
The reg_read/write() fields of struct nvmem_device point to memory owned
by the nvmem provider. They must not be dereferenced after the provider
is unregistered. Ahead of protecting against accesses to invalid memory
with SRCU, move the callbacks into a separate structure the address of
which is stored in nvmem_device.
