Subject: [PATCH v2] x86/PCI: Correct warnings about missing or incorrect SPDX license headers.

Add the missing "SPDX-License-Identifier" license header
to the arch/x86/pci/numachip.c (use the GPL-2.0 identifier
derived using the comment mentioning license from the
top of the file), and remove license boilerplate as per
a similar commit 8cfab3cf63cf ("PCI: Add SPDX GPL-2.0 to
replace GPL v2 boilerplate").

Correct existing SPDX license header in the files
drivers/pci/controller/pcie-cadence.h and
drivers/pci/controller/pcie-rockchip.h to use
correct comment style as per the section 2 "Style"
of the "Linux kernel licensing rules" (see:
Documentation/process/license-rules.rst).

Both changes will resolve the following checkpatch.pl
script warning:

WARNING: Missing or malformed SPDX-License-Identifier tag in line 1

Signed-off-by: Krzysztof Wilczynski <kw@...ux.com>
---
Changes in v2:
  Update wording and mention checkpatch.pl script warnings.
  Add two C header files to which the fix also applies.
