There is no possible for platform_get_irq() to return 0,
and the return value of platform_get_irq() is more sensible
to show the error reason.

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it might not be relevant here). This
also fixes !CONFIG_OF error:
drivers/media/cec/platform/tegra/tegra_cec.c:457:34: error: ‘tegra_cec_of_match’ defined but not used [-Werror=unused-const-variable=]

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

tegra_cec_probe() and tegra_cec_resume() ignored possible errors of
clk_prepare_enable(). The patch fixes this.

Most CEC platform drivers are using VIDEO_*_CEC pattern, some with
an _HDMI extension too.
Well, they're not related to V4L2 support, and we don't really
need those big config names. So drop VIDEO_* from them, remove
_HDMI (if present) and move CEC to the start.
This way, all platform driver options are now CEC_<driver>.

As CEC support doesn't depend on MEDIA_SUPPORT, let's
place the platform drivers outside the media menu.
As a side effect, instead of depends on PCI, seco driver
can select it (and DMI).
