Masahiro Yamada 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.

Joachim Eastwood 88806daf10 nvmem: add NXP LPC18xx OTP driver
Add simple read only driver for the internal OTP (One Time Programmable)
memory found on all NXP LPC18xx and LPC43xx devices.

The OTP memory is split into 4 banks each with 4 32-bits word. Some of
the banks contain predefined data while others are for general purpose
and user programmable via the OTP API in ROM. Note that writing to the
OTP memory is not yet supported.
