The i.MX7S/D takes the bank address in the CTRLn.ADDR field and the data
value in one of the DATAx {0, 1, 2, 3} register fields. The current write
routine is based on writing the CTRLn.ADDR field and writing a single DATA
register only.

i.MX7S/D have a different scheme for addressing the OTP registers inside
the OCOTP block. Currently it's possible to address the wrong OTP registers
given the disparity between IMX6 and IMX7 OTP addressing.

Since OTP programming is one-time destructive its important we restrict
this interface ASAP.

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.

drivers/nvmem/qfprom.c:76:22:    got void [noderef] <asn:2>*[assigned] base

The type of nvmem_config->priv is (void *), so sparse complains
about assignment of the base address with (void __iomem *) type.

Even if we cast it out, sparse still warns:
warning: cast removes address space of expression

Of course, we can shut up the sparse by marking __force, but a more
correct way is to put the base address into driver private data.

Hyper-V allows the guest to report panic and the guest can pass additional
information. All this is logged on the host. Currently Linux is passing back
information that is not particularly useful. Make the following changes:

1. Windows uses crash MSR P0 to report bugcheck code. Follow the same
convention for Linux as well.
2. It will be useful to know the gust ID of the Linux guest that has
paniced. Pass back this information.

These changes will help in better supporting Linux on Hyper-V
