s390/Kconfig: default PCI_NR_FUNCTIONS to 512

Browse Source 
With the addition of more complete SR-IOV support, we are recommending
to raise this limit for distributions to 512, as the previous default of
128 can easily be hit with just the VFs of a single PCI physical
function.
With at least one distribution now shipping with this, supporting
only one fourth as many PCI functions on a default upstream build may
lead to confusion and reduced testing of the higher limit so increase
the default to 512.

This allows you to specify the maximum number of PCI functions which
this kernel will support.
