Currently its not possible to build PCIE_CADENCE_PLAT_HOST/EP drivers as
modules (symbols are bool only).
PCIe is not necessary for basic boot either. So, I can drop these
configs until these drivers are build able as modules, if you prefer.

Is PCIe required for basic boot for the other platforms in the defconfig
which do enable it in the defconfig today?  It is required for non-basic
boot (whatever storage one puts in a PCIe slot).  If someone is going to
be fixing the PCIe driver to be able to be modular, that's fine too but
I ran in to this trying to see what works out of the box in the
defconfig, on this platform and hit both of these rather large
omissions.

If PCI is often used for storage, then that's ok. There are a number of
other platforms where PCIe is only used for wireless networking or
other secondary devices, but they are still built-in because they got
added before it became possible for PCIe host drivers to be loadable
modules. I would like to eventually go through and turn those into
loadable modules, but for the moment it would be good to only add
built-in drivers where this is actually useful.
