In mx2_camera_try_fmt(), when applying i.MX25 restrictions to frame sizes,
the height is checked to be <= 0xffff. But later an integer multiplication
height * 4 * 0x3ffff is performed, which will overflow even for bounded
height values. This patch switches to using 64-bit multiplication and
division to avoid overflowing.

Add a capabilities field to the soc_camera_host structure to flag hosts
that support user-configurable line strides. soc_camera_try_fmt() then
passes the user-provided bytesperline and sizeimage format fields to
such hosts, and expects the host to check (and fix if needed) the
values.

Enable the LNA amplifier also for DVB-T (like for DVB-T2 and DVB-C);
this greatly improves reception of weak signals without affecting the reception
of the strong ones.
Experimental data (collected with the mipsel STB) on the weakest frequencies
available in my area:
LNA OFF:
MUX level BER picture
RAI mux 4 72% 32000 corrupted
TIMB 2 75% 14 OK
TVA Vicenza 68% 32000 corrupted
RAI mux 2 78% 14 OK
LNA ON:
MUX level BER picture
RAI mux 4 73% 1500 OK
TIMB 2 76% 0 OK
TVA Vicenza 69% 0 OK
RAI mux 2 79% 0 OK
Moreover, with LNA enabled, the PCTV 290e was able to pick up 2 new frequencies
matching the integrated tuner of my Panasonic G20 TV, which is really good.

As reported by Masanari, this macro is using "KERN_ERR"
instead of "KERN_ERROR". That would lead into a compilation
breakage, if this macro were used somewhere inside the driver.
Instead of fixing the macro, as originally proposed, let's just
remove the dead code.

If the V4L2_EVENT_SUB_FL_SEND_INITIAL was set, then the application expects
to receive an initial event of the initial value of the control.
However, commit c53c2549333b340e2662dc64ec81323476b69a97 that added the new
v4l2_subscribed_event_ops introduced a regression: while the code still queued
that initial event the __v4l2_event_queue_fh() function was modified to ignore
such requests if sev->elems was 0 (meaning that the event subscription wasn't
finished yet).
And sev->elems was only set to a non-zero value after the add operation
returned.
This patch fixes this by passing the elems value to the add function. Then the
add function can set it before queuing the initial event.

For the ov7670 camera to return images at the requested frame rate,
it needs to make calculations based on the clock speed, which is
a completely external factor (depends on the wiring of the system).
On the XO-1.5, which is the only known via-camera user, the camera
is clocked at 90MHz.
Pass this information to the ov7670 driver, to fix an issue where
a framerate of 3x the requested amount was being provided.
