Add a mask parameter to control the lookup of the PCI region from which
the mapping can be made.

Evolve dm_pci_map_bar() to include an offset and length parameter. These
allow a portion of the memory to be mapped and range checks to be
applied.
Passing both the offset and length as zero results in the previous
behaviour and this is used to migrate the previous callers.

Use the new sequence number in all cases. Drop the logic to check for a
valid number in designware_i2c, since it will always be valid.
Also drop the numbering in the uclass, since we can rely on driver
model giving us the right sequence numbers.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This patch adds support for the SMBus block read/write functionality.
Other protocols like the SMBus quick command need to get added
if this is needed.
This patch also removed the SMBus related defines from the Ivybridge
pch.h header. As they are integrated in this driver and should be
used from here. This change is added in this patch to avoid compile
breakage to keep the source git bisectable.
Tested on a congatec BayTrail board to configure the SMSC2513 USB
hub.

The i2c uclass has a default setting for per_child_platdata_auto_alloc_size
so drivers do not need to set it. Remove this from drivers to avoid
confusion.

This is used on most Intel platforms. We don't have a driver for it yet, but
add a stub to handle the init. For now this targets ivybridge so we may want
to add a device tree binding and generalise it when other platforms are
supported.
