HV: fix bug change default vuart IRQ for UP2 board

Browse Source 
now UP2 board use ttyS1 as debug uart in HV, and vuart ttyS0 in
SOS kernel (acrn.conf default configure), its default IRQ is 4,
but SOS kernel will also assign IRQ4 to its ttyS1, they're sharing
one IRQ, and it can cause SOS boot hung issue, for HV not support
sharing IRQ now.

some boards use ttyS0 as debug uart, it has not this issue; for that
board, SOS will assign IRQ5 to its ttyS1, no sharing IRQ.

change it to IRQ6 to avoid the issue.
