acrn-config: insert vbdf in hex format and vuart vbdf logic 

Bug fix:
1. The bdf were inserted in decimal. Fix it with hexadecimal
format.
2. The vuart vbdf will only take the dev which no used bdf has
the same dev. For example: If 00:01.1 is in used but not 00:01.0,
vuart vbdf will skip 00:01.0 and look for 00:02.0, 00:03.0 and so on.
