qemu-arm64: refactor 'console=hvc0,hvc1' for kata-agent debugging

Since kata-agent is using virtio-console to output debugging info
and the console ports are available in the guest as /dev/hvc0 and
/dev/hvc1, we should swap origin console type 'console=ttyAMA0'
with 'console=hvc0,hvc1'.

Fixes: #1033
