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).

The Amlogic G12A SoC embeds a second CEC controller with a totally
different design.
The two controller can work in the same time since the CEC line can
be set to two different pins on the two controllers.
This second CEC controller is documented as "AO-CEC-B", thus the
registers will be named "CECB_" to differentiate with the other
AO-CEC driver.
Unlike the other AO-CEC controller, this one takes the Oscillator
clock as input and embeds a dual-divider to provide a precise
32768Hz clock for communication. This is handled by registering
a clock in the driver.
Unlike the other AO-CEC controller, this controller supports setting
up to 15 logical addresses and supports the signal_free_time settings
in the transmit function.
Unfortunately, this controller does not support "monitor" mode.

The Amlogic SoC embeds a standalone CEC controller, this patch adds a driver
for such controller.
The controller does not need HPD to be active, and could support up to max
5 logical addresses, but only 1 is handled since the Suspend firmware can
make use of this unique logical address to wake up the device.
The Suspend firmware configuration will be added in an other patchset.
