Since 79c987de8b354, enumerating framesize on format set with "MODE_NONE"
(any raw formats) is reporting an invalid frmsize.
Size: Stepwise 0x0 - 0x0 with step 0/0
Before this change, the driver would return EINVAL, which is also invalid but
worked in GStreamer. The original intent was not to implement it, hence the
-ENOTTY return in this change. While drivers should implement ENUM_FRMSIZE for
all formats and queues, this change is limited in scope to fix the regression.
This fixes taking picture in Gnome Cheese software, or any software using
GSteamer to encode JPEG with hardware acceleration.
Fixes: 79c987de8b354 ("media: hantro: Use post processor scaling capacities")

Thanks a lot for this Christmas present, confirmed that it fixes the
affected apps / use-cases for me :)
