Subject: [PATCH v2] PCI: controller: add missing MODULE_DESCRIPTION()
 macros

When ARCH=x86, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/pci/controller/dwc/pci-exynos.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/pci/controller/pci-host-generic.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/pci/controller/pcie-altera.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/pci/controller/pcie-altera-msi.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/pci/controller/pcie-mediatek.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/pci/controller/pcie-mediatek-gen3.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/pci/controller/vmd.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/pci/controller/pcie-apple.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/pci/controller/pcie-mt7621.o

Add the missing invocations of the MODULE_DESCRIPTION() macro.

Corrections to these descriptions are welcomed. I'm not an expert in
this code so in most cases I've taken these descriptions directly from
code comments, Kconfig descriptions, or git logs.  History has shown
that in some cases these are originally wrong due to cut-n-paste
errors, and in other cases the drivers have evolved such that the
original information is no longer accurate.

Also let me know if any individual changes need to be split into a
separate patch to go through a separate maintainer tree.

Changes in v2:
- no changes to the actual patch, just rebased to recent linus/master
  and collected the tags received so far
- Link to v1: https://lore.kernel.org/r/20240610-md-drivers-pci-controller-v1-1-b998c242df55@quicinc.com
