Patch to add PCI IDs for HSUART on Intel Atom SOC

HSUART devices not recognized on Intel Atom Cherry Trail SOCs. 

As a consequence boot halts during uart.1 initialization unless disabled or
commented out in the default device.hints.

The attached patch adds PCI IDs for 0x228a8086 and 0x228c8086 to
uart_bus_pci.c.

HSUART#1 is tested and seem to function normally.
HSUART#2 is not tested.
