Jian Jun Chen cee45a80d9 hv: add default handlers for PIO/MMIO access
Add the default handlers for PIO and MMIO access which returns all
FFs on read and discards write. These default handlers are registered
when SOS VM or pre-launched VM is created.

v3 -> v4:
- use single layer if in hv_emulate_pio
- change the implementation of pio_default_read

v2 -> v3:
- use runtime vm type instead of CONFIG_PARTITION_MODE
- revise the pio/mmio emulation functions
- revise the pio/mmio default read functions according to MISRA C
- revise the commit message

v1 -> v2:
- add default handlers members in struct acrn_vm and add interfaces
  to register default handlers for PIO and MMIO.
