This change fixes the issue when SAMv7 GMAC sometimes does not start packet
transmission. The issue is that EMAC_NCR_TSTART is written to EMAC_NCR register
while tx descriptor is not delivered to memory.

According to the current implementation, "cxd56_cpu1siguninit" will only
be called once during the NuttX startup phase,
and it won't involve scenarios of multi-threaded concurrent access.

Some SD card connectors do not have separate card detection pin. In that
case card detection has to be done on CD/DAT3 data line. This means
software (i.e. architecture level driver) has to take care of pin
configuration switching (pin has to be set as data pin in case of
transfer and as interrupt card detection pin when there is no action
on data line).
This commit adds CD/DAT3 line card detection support for SAMv7 MCU.

Current implementation of QSPI in SPI mode was available only for MCUs
that do not have standard SPI at all. MCUs with both QSPI and SPI can
however also use QSPI in SPI mode and thus have one more SPI bus. This
commit adds required defines and config options to support QSPI in SPI
mode for all SAMv7 MCUs.

After sevaral resets of the chip after programming, rptun stops working correctly.
Simple test with RPMSG UART causes a lock:
on the netcore:
nsh>cat /dev/ttyproxy
on the appcore:
nsh>echo xxx > /dev/ttyproxy
The problem doesn't occur with NRF53_FLASH_PREFETCH=n
after the follow patch:

virtio: add virtio framework in NuttX
1. virtio devics/drivers match and probe/remote mechanism;
2. virtio mmio transport layer based on OpenAmp (Compatible with both
virtio mmio version 1 and 2);
3. virtio-serial driver based on new virtio framework;
4. virtio-rng driver based on new virtio framework;
5. virtio-net driver based on new virtio framework
(IOB Offload implementation);
6. virtio-blk driver based on new virtio framework;
7. Remove the old virtio mmio framework, the old framework only
support mmio transport layer, and the new framwork support
more transport layer and this commit has implemented all the
old virtio drivers;
8. Refresh the the qemu-arm64 and qemu-riscv virtio related
configs, and update its README.txt;
New virtio-net driver has better performance
Compared with previous virtio-mmio-net:
