drivers: bcm2835_unicam: Disable trigger mode operation
On a Pi3 B/B+ platform the imx219 sensor frequently generates a single corrupt
frame when the sensor first starts. This can either be a missing line, or
invalid samples within the line. This only occurrs using the Unicam kernel
driver.
Disabling trigger mode elimiates this corruption. Since trigger mode is a
legacy feature copied from the firmware driver and not expected to be needed,
remove it. Tested on the Raspberry Pi cameras and shows no ill effects.

staging: fbtft: Add minipitft13 variant
The Adafruit Mini-PiTFT13 display needs offsets applying when rotated,
so use the "variant" mechanism to select a custom set_addr_win method
using a dedicated compatible string of "fbtft,minipitft13".

staging/bcm2835-camera: Add support for DMABUFs
DMABUFs are all handled by videobuf2, so there is no reason not
to enable support for them.
Note that this driver is still using the vmalloc allocator, so
the buffers it allocates will not be compatible with the codec
or ISP driver that require contiguous buffers. However this
driver should be able to import the buffers allocated by them.

Previously they were returning positive non-zero codes for success,
which were getting passed up the call stack. Since release 4.19,
do_dentry_open (fs/open.c) has been catching these and flagging an
error. (So this driver has been broken since that date.)

Vision Components have made an OV9281 module which blocks reading

so doesn't allow auto-increment register reading as used when
reading the chip ID.
Use two reads and manually combine the results.
