HV: change serial PCI cfg to bus:dev.func format

Browse Source 
before PCI_BDF uses its hex value like "0xC2" for "0:18.2" to
configure, now use "0:18.2" directly to make it more readable
and easier to configure.

A 16-bit integer encoding bus, device and function of the serial PCI device.
This integer consists of 8-bit bus ID, 5-bit device ID and 3-bit function ID.
As an example,for PCI device 00:18.2, this BDF would be (0 << 8) | (0x18 << 3)
| (2 << 0), it's 0x00C2.
BDF: bus, device and function of the serial PCI device; for an example,
PCI device ttyS2: 0:18.2.
