Yay. My camera works now. 

Thanks to https://github.com/OpenIPC/firmware/issues/759, it seems that my
T31L also needs `isp.blkCnt=1`, let's document this so that others can find
it.

It does appear that `package/ingenic-osdrv-t31/files/script/load_ingenic`
should do this, I have no idea why it didn't do that on my camera. The
tinkering continues.

## Troubleshooting: Majestic does not show any images, no reboot
Let's say that `top` shows that majestic is running, but no image is displayed.
The preview tab shows only a test pattern and there is an error similar to the
one below in dmesg.
```
...
sc2336 chip found @ 0x30 (i2c0)
sensor driver version H20210805a
sc2336 stream on
error: one buffer schedule only support nrvbs = 1, chan index:0, num_buffers:2
...
```
The `nrvbs = 1` may be the problem. Set the `isp.blkCnt` majestic property
to 1 with the Block Count control on the ISP tab of Majestic settings, then
restart majestic.
This issue has only been documented on T31L and T31N SOCs with SC2336 and
JXF37 sensors; let us know if you see this on a different platform an if this
setting change works for you.
