SPDX: Convert all of our single license tags to Linux Kernel style

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.

pci: xilinx: Use pci_generic_mmap_{read, write}_config()

Use the new helper function to avoid boilerplate in the driver.

Note that this changes __raw_writel et al. to writel. AFAICT this is
no prob

pci: xilinx: Use pci_generic_mmap_{read, write}_config()

Use the new helper function to avoid boilerplate in the driver.

Note that this changes __raw_writel et al. to writel. AFAICT this is
no problem because:

- The Linux driver for the same hardware uses the non-__raw variants as
well (via pci_generic_config_write()).
- This driver seems to be used only on MIPS so far, where the __raw and
non-__raw accessors are the same.

treewide: replace with error() with pr_err()

U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h

treewide: replace with error() with pr_err()

U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

# define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
(...)
// </smpl>

This patch adds a driver for the Xilinx AXI bridge for PCI express, an
