- There are occasional extra STOPs being sent due to an IP bug when using an
FPGA based I2C. Add a flag "inflight" to mask out extra STOP interrupts when
using the FPGA based implementation
- There are no MPFS_I2C_ST_STOP_SENT irq's "initally". It is just already
either success or still in progress

The framebuffer of the emulator is a single buffer mode, and the pan_display method is not implemented, so as long as the fb device is created and poll notify once, the fb can be kept in a writable state.

The typo s/.timid/.tcid prevents to compile NuttX with
quadrature encoder configured for timer1 (CONFIG_SAMV7_TC1_QE)
and s/SAM_TC789_BASE/SAM_TC678_BASE prevented use of the
of the timer 2.

Summary:
Adding virtual evaluate platform GoldFish. Which is based on
Android Goldfish Emulator, it's a ARM virt board but Android
enhance it with more featue.
The patch set goldfish as a arm chip.

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.

Workaround to avoid deadlock situation: The RX shall not try to wait for complete
frame in case there is RX errors detected.
In case mpfs_receive is called, it keeps waiting for complete frame and
also keeps the net_lock locked. In the mean while, the TX may run out of free
descriptors, but can not get net_lock mutex lock to be able to release used
descriptors. If there are no free TX descs it disables RX interrupts because
it may require to send response to the received frame.
So, TX side keeps RX interrupts disabled due to lack of free descriptors and
RX blocks TX to release those descs by stubbornly waiting for complete frame.
RPMSG is associated with the use of HPWORK / LPWORK queues.
After sending a message to the remote end (Linux), the system
waits for an ack before proceeding. Unfortunately this may
take sometimes more time than one would expect. Ack waiting is
also unnecessary: nothing is done with that information. Even
worse, the net_lock() is also held during the blocked time so
it blocks other network stacks that are unrelated to this.
Also reorganize the mpfs_opensbi_*.S so that the trap
handler is easily relocated in the linker .ld file without
the need to relocate the utils.S. This makes it easier to
separate the files into own segments. The trap file should be
located in the zero device.
Moreover, provide support for simultaneous ACK and message
present handling capabilities in both directions. There are
times when both bits are set but only other is being handled.
In the end, the maximum throughput of the RPMSG bus increases
easily 10-20% or even more.

The master clock frequency should be multiple of the sample rate
and bit clock at the same time. Then, check if the current master
clock satisfies such a condition and set it accordingly otherwise.
In order to gracefully stop the I2S stream, add an interface to set
a `streaming` status variable that sets the `AUDIO_APB_FINAL` flag
that will be handled by the upper layers of the audio subsystem.
