Now the io_emul.c is relates with arch,io_req.c is common,
move some APIs from io_emul.c to io_req.c as common like these APIs:
register_pio/mmio_emulation_handler
dm_emulate_pio/mmio_complete
pio_default_read/write
mmio_default_access_handler
hv_emulate_pio/mmio etc

For Pre-launched VMs, ACRN uses mptable for reporting APIC IDs to guest OS.
In current code, ACRN uses physical LAPIC IDs for vLAPIC IDs.
This patch is to let ACRN use vCPU id for vLAPIC IDs and also report the same
when building mptable. ACRN should still use physical LAPIC IDs for SOS
because host ACPI tables are passthru to SOS.

Add SDC ACPI device in dsdt, and assign GPIO 0 to SDC for SD card
detection.
Currently, the SD card hotplug function needs to insert SD card when
system boot, otherwise, it does not work. Since it needs P2SB virtualization
to set SD card presence state, and P2SB does not support user space interfaces
so this is an known issue.

GPIO set/get value can be operated by accessing PIO space and the PIO
register definition for GPIO is in gpio_dm.h, frontend driver or ACPI
control methods can operate GPIO based on it.
GPIO mediator also defines ACPI control methods to support GPIO
operations, GPIO consumers can invoke PIO_GPIO_SET_VALUE/PIO_GPIO_GET_VALUE
in their own DSDT to set/get one GPIO value via ACPI control method.
v2: 1) Fix code style.
2) Use virtio configuration space callbacks to implement GPIO PIO operations
that replace pci_gpio_read/pci_gpio_write with virtio_cfgread/virtio_cfgwrite.
3) Return 0xFFFFFFFF as invalid result of PIO reading instead 0.
