this patch drops reserving contigiuos memory for the device,
as now with CMA support there is no need of this.
This patch also prepares to removal of config_params.

this patch adds support to use v4l2_fh_open() and vb2_fop_release,
which allows to drop driver specific struct vpif_fh, as this is handeled
by core. This patch also drops vpif_g/s_priority as this handeled
by core.

There are certain client bugs (double unmap, for example) that can cause
the handle->kmap_cnt (an unsigned int) to wrap around from zero. This
causes problems when the handle is destroyed because we have:
while (handle->kmap_cnt)
ion_handle_kmap_put(handle);
which takes a long time to complete when kmap_cnt starts at ~0 and can
result in a watchdog timeout.
WARN and bail when kmap_cnt is about to wrap around from zero.

this patch drops unnecessary check from start_streaming() callback
as this is already done in try/s_fmt and some minor code cleanups,
drops check for vb2_is_streaming() as this check is done by vb2
itself before calling this callback.

Toradex Colibri Evaluation Board uses the DS1307 RTC and the
MCP251x CAN controller. The NVIDIA Tegra 3 based Colibri T30
module can be used on this carrier board, hence enable those

Furthermore the NVIDIA Tegra 3 based Apalis T30 module too

Nobody is maintaining SMTC anymore and there also seems to be no userbase.
Which is a pity - the SMTC technology primarily developed by Kevin D.
Kissell <kevink@paralogos.com> is an ingenious demonstration for the MT
ASE's power and elegance.
Based on Markos Chandras <Markos.Chandras@imgtec.com> patch
https://patchwork.linux-mips.org/patch/6719/ which while very similar did
no longer apply cleanly when I tried to merge it plus some additional
post-SMTC cleanup - SMTC was a feature as tricky to remove as it was to
merge once upon a time.
