There is no good reason to duplicate the PCI menu in every architecture.
Instead provide a selectable HAS_PCI symbol that indicates availability
of PCI support and the handle the rest in drivers/pci.

Note that for powerpc we now select HAVE_PCI globally instead of the
convoluted mess of conditional or or non-conditional support per board,
similar to what we do e.g. on x86.  For alpha PCI is selected for the
non-jensen configs as it was the default before, and a lot of code does
not compile without PCI enabled.  On other architectures with limited
PCI support that wasn't as complicated I've left the selection as-is.

Just in case, could you double-check these?
PCI_ENDPOINT
PCI_ENDPOINT_CONFIGFS
PCI_EPF_TEST


Previously, architecture without "source drivers/pci/Kconfig"
could not enable PCI_ENDPOINT.

Now, any architecture can enable it
regardless of its actual PCI availability
because PCI_ENDPOINT is only guarded by HAS_DMA.


We could add 'depends on HAVE_PCI' or something
to guard it to avoid changing the logic.


config PCI_ENDPOINT
        bool "PCI Endpoint Support"
        depends on HAVE_PCI     # Is this correct ??
        depends on HAS_DMA


or better to have 'depends on PCI' ?


PCI ML is also CC'ed, so comments are appreciated.

This change doesn't make sense as there's no PCI hardware in the Xtensa ISS.
Otherwise for the Xtensa part:

I guess that makes sense.

It does not depend on the normal PCI support, so I don't think this
is the right thing to do.
