HV: change vuart port (used by SOS) to ttyS2

Browse Source 
On MRB, there are some differences for SOS uart setting between
debug version and release version:
  for debug version, ttyS0 is vuart, ttyS1 is 00:18.0, ttyS2 is 00:18.1,
    ttyS3 is 00:18.3.
  for release version, ttyS0 is 00:18.0, ttyS1 is 00:18.1, ttyS2 is
00:18.2, ttyS3 is 00:18.3. There is no vuart.

port: 00:18.0 is for bluetooth usage, ttyS0 can't be used as SOS console
for release build.

after change, debug build: vuart -->ttyS2 (SOS console);
release version: ttyS2; 00:18.2, it can be used as SOS console too.

for UEFI platform, also change acrn.conf console=ttyS0-->ttyS2
to matched with vart change.
