sh: drivers: convert to SPDX identifiers

Update license to use SPDX-License-Identifier instead of verbose license
text.

As original license mentioned, it is GPL-2.0 in SPDX.
Then, MODULE_LICENSE() should be "GPL v2" instead of "GPL".
See ${LINUX}/include/linux/module.h

"GPL" [GNU Public License v2 or later]
"GPL v2" [GNU Public License v2]

sh: pci: Convert to upper/lower_32_bits() helpers.

Instead of hand-rolling our own, just use the generic ones instead.

sh: pci: Use I/O accessors consistently in SH7786 PCIe init code.

Some of the existing code is flipping between __raw_xxx() and
pci_{read,write}_reg(). As the latter are just wrappers for the former,
flip over to using them consistently.

sh: Fix up multi-resource mapping for SH7786 PCIe.

This reworks some of the SH7786 PCIe initialization code to dynamically
setup and size the various resource windows, as opposed to the original
code that simply wired in a couple of them statically.

At the same time, we tidy up the initialization code a bit, kill off some
read-only register twiddling that was gleaned from the bus analyzer, and
also propagate the physical slot/channel mapping.

sh: Fix up SH7786 PCI resource definitions.

This adds in some of the missing memory resources for channels 1/2 and
gets the code building again for the recent changes.

sh: pci: SH7786 PCI ops.

This adds in preliminary support for the SH7786 PCIe module PCI ops,
and the corresponding module definitions.
