When updating the crop rectangle during streaming, the IRQ handler will
reprogram the resizer after the current frame. A race condition
currently exists between the set selection operation and the IRQ
handler: if the set selection operation is called twice in a row and the
IRQ handler runs only during the second call, it could reprogram the
hardware with partially updated values. Use a spinlock to protect
against that.

The resizer_set_input_size() function prints a debugging message with
the input width and height values. As the function is called from
interrupt context, printing that message to the serial console could
slow down the interrupt handler and cause it to miss the start of the
next frame, causing image corruption.
Fix this by reorganizing the resizer debug messages. The driver now
prints the input size, the crop rectangle and the output size in the set
selection handler instead of scattering debug messages in various
places.

In BT.656 mode the synchronization signals are generated by the CCDC
from the embedded sync codes. The VD0 and VD1 interrupts are thus only
triggered when the CCDC is enabled, unlike external sync mode where the
line counter runs even when the CCDC is stopped. We can't disable the
CCDC at VD1 time, as no VD0 interrupt would be generated for a short
frame, which would result in the CCDC being stopped and no VD interrupt
generated anymore. The CCDC is stopped from the VD0 interrupt handler
instead for BT.656.

Checking that the captured field corresponds to the last required field
depending on the requested field order before completing the buffer
isn't enough. When the first field at stream start corresponds to the
last required field, this would result in returning an interlaced buffer

Fix this by keeping track of the fields captured in the buffer, and make
