NB (Intel Document Number 336256-004US):
1. The E3900 and A3900 Series Processors support four LPSS_UART ports,
while the N- and J- Series Processors support only LPSS_UART [2:1]
ports.
2. The LPSS_UART1 port is dedicated for discrete Global Navigation
Satellite System (GNSS). This port can be used for generic UART
functionality if GNSS is not used.
3. The LPSS_UART2 port is dedicated for host OS debug.
4. The LPSS_UART0 and LPSS_UART3 ports are for generic UART functionality.
5. Only UART [1:0] ports support DMA.
