serial: 8250_lpss: Enable HS UART on Elkhart Lake 



Intel Elkhart Lake may use High Speed UART from OSE IP block.
This is different to what we have in main LPSS, though compatible
with older version of it, which is handled by this driver.

Enable OSE HS UART on Intel Elkhart Lake by adding PCI IDs.
