55f47d2299 OvmfPkg/Microvm: wire up serial console, drop super-io 
Microvm has no LPC bridge, so drop the PciSioSerialDxe driver.
Use SerialDxe instead, with ioport hardcoded to 0x3f8 aka com1 aka ttyS0.

With this tianocore boots to uefi shell prompt on the serial console.
Direct kernel boot can be used too.

76602f45dc OvmfPkg/Microvm: use XenTimerDxe (lapic timer) 
Microvm has no acpi timer, so go use XenTimerDxe
which uses the local apic instead.

Set PcdFSBClock to 1000 MHz, which is the lapic
timer frequency used by KVM.

Guests depending on BIOS will probably not work that well with microvm
due to legacy hardware being not available.
