doc: Update the com1,com2 section with pci and amt options.
The "xen: Automatically find serial port on PCI/PCIe and AMT devices."

Xen supports up to two 16550-compatible serial ports. For example:
`com1=9600, 8n1, 0x408, 5' maps COM1 to a 9600-baud port, 8 data
bits, no parity, 1 stop bit, I/O port base 0x408, IRQ 5. If some

only a prefix of the full configuration string need be specified. If
the baud rate is pre-configured (e.g., by the bootloader) then you
can specify `auto' in place of a numeric baud rate.
+ For PCI serial devices, such as Intel AMT you can use the {\bf amt}
+ option to automatically find the I/O base. For PCI serial devices,
+ such as NetMos, you can use {\bf pci} to probe for the I/O base.
+ Both options will set the IRQ to zero - meaning they will poll the device.
