serial: 8250_pci: Enumerate Elkhart Lake UARTs via dedicated driver

Elkhart Lake UARTs are PCI enumerated Synopsys DesignWare v4.0+ UART
integrated with Intel iDMA 32-bit DMA controller. There is a specific
driver to handle them, i.e. 8250_lpss. Hence, disable 8250_pci
enumeration for these UARTs.

Fixes: 1b91d97 ("serial: 8250_lpss: Add ->setup() for Elkhart Lake ports")
Fixes: 4f912b8 ("serial: 8250_lpss: Enable HS UART on Elkhart Lake")
