During a memcpy from a pmem device, if a machine check exception is
generated we end up in a panic. In case of fsdax read, this should
only result in a -EIO. Avoid MCE by implementing memcpy_mcsafe.
Before this patch series:
```
bash-4.4# mount -o dax /dev/pmem0 /mnt/pmem/
[ 7621.714094] Disablin
schedule_work() cannot be called from MCE exception context as MCE can
interrupt even in interrupt disabled context.

If you use lseek or similar (e.g. pread) to access
a location in a seq_file file that is within a record,
rather than at a record boundary, then the first read
will return the remainder of the record, and the second
read will return the whole of that same record (instead
of the next record).

For pages that were retained via get_user_pages*(), release those pages
via the new put_user_page*() routines, instead of via put_page() or

- Update the devicetree binding document to support the imx7ulp mu.
- Rebase the patch refer to the following bug-fixs patch-set issued
by Daniel Balut
There is a version 1.0 MU on i.MX7ULP platform.
One new version ID register is added, and it's offset is 0.
TRn registers are defined at the offset 0x20 ~ 0x2C.
RRn registers are defined at the offset 0x40 ~ 0x4C.
SR/CR registers are defined at 0x60/0x64.
Extend this driver to support it.

Tx doorbell is handled by txdb_tasklet and doesn't
have an associated IRQ.
Anyhow, imx_mu_shutdown ignores this and tries to
free an IRQ that wasn't requested for Tx DB resulting
in the following warning:
