Add Apollo Lake SIO/LPSS UARTs PCI IDs

Browse Source 
Add PCI IDs for Intel Apollo Lake Series HSUARTs:

    # pciconf -ll
    drv   selector      class    rev  hdr  vendor device subven subdev
    uart0@pci0:0:24:0:  118000   0b   00   8086   5abc   8086   7270
    uart1@pci0:0:24:1:  118000   0b   00   8086   5abe   8086   7270
    uart2@pci0:0:24:2:  118000   0b   00   8086   5ac0   8086   7270
    uart3@pci0:0:24:3:  118000   0b   00   8086   5aee   8086   7270

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.
