Apple SoCs have an integrated NVMe controller that isn't connected
over a PCIe bus. In preparation for adding support for this NVMe
controller, split out the PCI support into its own file. This file
is selected through a new CONFIG_NVME_PCI Kconfig option, so do
a wholesale replacement of CONFIG_NVME with CONFIG_NVME_PCI.

This probably should have been done a while back since it is a core
system. Very few boards remain to be migrated.
Addd a migration deadline for a year out.

Some boards still use the old timer mechanism. Set a deadline for them to
update to driver model. Point to some examples as well.
This needs a bit of a strange rule to avoid an error on some boards.

Convert some of these occurences to C code, where it is easy to do. This
should help encourage this approach to be used in new code.

Now that we have a 'positive' Kconfig option, use this instead of the
negative one, which is harder to understand.

Add a few more details to the documentation.

Driver model uses quite strong conventions on error codes, but these are
currently not clearly documented. Add a description of the commonly used
errors.
