PCI: dw-rockchip: Endpoint mode cannot raise INTx interrupts

Neither RK3568 or RK3588 supports INTx interrupts.

Since epc_features is zero initialized, this is strictly not needed.
However, setting intx_capable explicitly to false makes it more clear
that neither RK3568 or RK3588 supports INTx interrupts.

No functional change.
