I2C status register reset value (0xf8) was not handled properly causing unnecessary bus resets.
Added critical section to mpfs_i2c_reset() and removed unnecessary interrupt disabling elsewhere.

- Change git repository urls to point to our tiiuae repos for nuttx & nuttx apps

…iver to re-initialize on rx timeout

If the interface is UP, and no packets are received in 30s, re-initialize the interface by calling the
already implemented mpfs_txtimeout_expiry.

This is a temporary workaround for a bug where IF might be UP and working but packets can only
be transmitted. Receive side just doesn't work at all.

The original bug can be re-produced easily by disconnecting and reconnecting the ethernet cable while
the IF is up.

SD-card clock speed is just forced to 50MHz. Note that to be correct, one should first set the SD-card
into high-speed mode, but currently NuttX doesn't support this.

With our cards, just setting the interface to 50MHz seems to work fine, and it removes the issue with
25MHZ clock causing disturbance on GPS bands. Typically cards which support high-speed mode just work with
50MHz interface clock.

This patch should be reverted when the NuttX supports high-speed mode, and we can properly set it.

…ardenedOS

In spi_irq handler the data is written into txfifo and transfer
is started before the TXDONE interrupt is cleared. If the bus/memory
access is in some cases delayed, the spi transfer may have been
finished already before the interrupt register is cleaned for the
transfer. This leads the early arrived interrupt to be just removed
and never handled, which would cause a timeout error.
This patch moves the clearing of the interrupt to the place before
the tx is started, so the interrupt is not missed in above cases.

If transfer is restarted in irq handler the interrupts shall be
cleared before the start bit is set in control register. This is
to avoid ints being accidentally cleared before they are handled leading
to timeout error.

This reverts commit d865823.

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.
