Add logic to enumerate sensor's frame size and interval.
Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

Allow the sensor to report the per-resolution frame interval.

It should be noticed that, despite the ov2680 datasheet says
that, for resolutions <= 1280x720, the sensor supports 60fps,
the data at ov2680.h tells otherwise, limiting it to 30fps.

Not sure yet if this is a limitation of atomisp or if it is
just because the tables are incorrect.
Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

If res-chg, VE_INTERRUPT_MODE_DETECT_WD irq will be raised. But
v4l2_input_status won't be updated to no-signal immediately until
aspeed_video_get_resolution() in aspeed_video_resolution_work().

During the period of time, aspeed_video_start_frame() could be called
because it doesn't know signal becomes unstable now. If it goes with
aspeed_video_init_regs() of aspeed_video_irq_res_change()
simultaneously, it will mess up hw state.
