hw/smbios: support for type 8 (port connector)

Browse source 
PATCH v1: add support for SMBIOS type 8 to qemu
PATCH v2: incorporate patch v1 feedback and add smbios type=8 to qemu-options

internal_reference: internal reference designator
external_reference: external reference designator
connector_type: hex value for port connector type (see SMBIOS 7.9.2)
port_type: hex value for port type (see SMBIOS 7.9.3)

After studying various vendor implementationsi (Dell, Lenovo, MSI),
the value of internal connector type was hard-coded to 0x0 (None).

Example usage:
-smbios type=8,internal_reference=JUSB1,external_reference=USB1,connector_type=0x12,port_type=0x10 \
-smbios type=8,internal_reference=JAUD1,external_reference="Audio Jack",connector_type=0x1f,port_type=0x1d \
-smbios type=8,internal_reference=LAN,external_reference=Ethernet,connector_type=0x0b,port_type=0x1f \
-smbios type=8,internal_reference=PS2,external_reference=Mouse,connector_type=0x0f,port_type=0x0e \
-smbios type=8,internal_reference=PS2,external_reference=Keyboard,connector_type=0x0f,port_type=0x0d
