Conghui Chen 859af9e03d DM: virtio-i2c: add backend interface

Add backend interface for virtio-i2c, it will parse the parameters,
maintain the info for native i2c device, remap the slave address and
dispatch the requirement from FE. When there is only one native adapter,
will not remap the slave address.

Usage for virtio-i2c:

virtio-i2c,<bus>[:<slave_addr>][:<slave_addr>]
	[,<bus>[:<slave_addr>][:<slave_addr>]]

e.g.
1.  virtio-i2c,4:1C
    SOS:
        mount /dev/i2c-4, slave addr is 0x1C.
    Guest OS:
        /dev/i2c-x
           |- 0x1C

2. virtio-i2c,4:1C:2F,6:70
    SOS:
        /dev/i2c-4, slave addr 0x1C and 0x2F
        /dev/i2c-6, slave addr 0x70
    Guest OS:
        /dev/i2c-x
           |- 0x1C
           |- 0x2F
           |- 0x70
