17eb18d674 nvmem: set nvmem->owner to nvmem->dev->driver->owner if unset 
All nvmem drivers are supposed to set the owner field of struct
nvmem_config, but this matches nvmem->dev->driver->owner.

As far as I see in drivers/nvmem/ directory, all the drivers are
the case.  So, make nvmem_register() set the nvmem's owner to the
associated driver's owner unless nvmem_config sets otherwise.

Remove .owner settings in the drivers that are now redundant.

e827756d64 nvmem: correct Broadcom OTP controller driver writes 
- use data write offset to write otp data instead of read offset
- use OTP program command 0x8 to write otp with ECC rather than just
command 0xA without ECC
