Cannonlake LPSS UART port can be working on both 32 bit and 8 bit mode.
To maintian compatibilty with previous generation of SOC, select 32 bit
mode as default.

Cannonlake SOC has two possible ways to make serial
console functional.
1. Legacy IO based access using Port 0x3F8.
2. LPSS UART PCI based access.
This patch to provide option to select index for LPSS
UART port: 0 = LPSS UART0, 1 = LPSS UART1, 2 = LPSS UART2
PCI based LPSS UART2 is by default enabled for Chrome Design.
