Enable 2 legacy serial ports for microdroid
Recent GKIs disable the 8250 serial core uarts by default, because it
was causing rogue MMIO accesses on ARM64. We need two, so this change
enables two again.
- /dev/ttyS0: console
- /dev/ttyS1: serial device to notify failure
Bug: 220071963
Test: boot microdroid and see /dev/ttyS0, /dev/ttyS1
Test: write to /dev/ttyS1 and see virtualizationservice log
