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.

Users of pthread_cond_wait() should take care of spurious wakeups and it
is usually used in conjunction with a predicate. Not doing so can result
in unintended behavior. For example:
virtio_net_tx_thread():
entry -> pthread_cond_wait() -> spurious wakeup ->
vq_clear_used_ring_flags() -> segfault (vq->used uninitialized)
tpm_crb_request_deliver():
entry -> pthread_cond_wait() -> spurious wakeup ->
swtpm_handle_request() called needlessly
virtio_rnd_get_entropy():
entry -> pthread_cond_wait() -> spurious wakeup ->
no avail ring processing ->
virtio_rnd_notify() skips pthread_cond_signal() due to
rnd->in_progress ->
vq_endchains() called needlessly ->
wait in pthread_cond_wait() indefinitely
Fix these uses of pthread_cond_wait() by using predicates.
The only use case without a clear predicate is the tx thread in
virtio-mei, because it works with two-dimensional linked lists.

- fix bugs and comments
