Subject: [PATCH] misc: define the MAX_VUART_NUM_PER_VM by offline tool

The current code define MAX_VUART_NUM_PER_VM for all VM and it's a hard
code which can't match our vUART logic which need dynamic setting.

This patch move the define of MAX_VUART_NUM_PER_VM to offline tool and
calculate it automatically.
