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.

--- Comment #1 from Johannes Lundberg <[hidden email]> ---
Additional info from atom-z8000-datasheet-vol-1.pdf

I think this SOC only has only one UART (integrated into the PCU) but two
Serial I/O HSUARTs.

The UART (uart.0) works with current 3F8h, IRQ4 settings.

The hint.uart.1.* settings from device.hints must be removed for this SOC since
uart1 and uart2 devices will be SIO High Speed UARTs.
