dt-bindings: PCI: host-generic-pci: Drop minItems and maxItems of ranges

Browse Source 
The ranges description states that "at least one non-prefetchable memory
and one or both of prefetchable memory and IO space may also be provided."

However, it should not limit the maximum number of ranges to 3.

Freescale LS1028 and iMX95 use more than 3 ranges because the space splits
some discontinuous prefetchable and non-prefetchable segments.

Drop minItems and maxItems. The number of entries will be limited to 32
in pci-bus-common.yaml in dtschema, which should be sufficient.

Fixes this CHECK_DTBS warning:
