[media] pulse8-cec: move out of staging
Now that the CEC framework has been moved out of staging and into the mainline kernel we can do the same for the pulse8-cec driver. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

-This driver needs to mature a bit more and another round of
-code cleanups.
-
-Otherwise it looks to be in good shape. And of course the fact
-that the CEC framework is in staging at the moment also prevents
-this driver from being mainlined.
-
-Some notes:
-
-1) Regarding the "autonomous" mode of the Pulse-Eight: currently this
-is disabled, but the idea is that this allows basic functionality
-when the PC is off, and it can wake-up the PC through USB.
-
-To prevent the device to go into autonomous mode the driver would
-have to send MSGCODE_SET_CONTROLLED 1 and then send a ping every
-30 seconds (in practice once every 15 seconds would be good). When
-powering off or going to standby send MSGCODE_SET_CONTROLLED 0 to
-turn the autonomous mode back on.
-
-This needs to be implemented in the driver. Autonomous mode was
-added in firmware v2.
-
-2) Writing to the EEPROM can only be done once every 10 seconds.
-
-3) To use this driver you also need to patch the inputattach utility,
-this patch will be submitted once this driver is moved out of staging.

- * - Devices with firmware version < 2 do not store their configuration in

- *
- * - In autonomous mode, only messages from a TV will be acknowledged, even
- * polling messages. Upon receiving a message from a TV, the dongle will
- * respond to messages from any logical address.
- *
- * - In autonomous mode, the dongle will by default reply Feature Abort
- * [Unrecognized Opcode] when it receives Give Device Vendor ID. It will
- * however observe vendor ID's reported by other devices and possibly
- * alter this behavior. When TV's (and TV's only) report that their vendor ID
- * is LG (0x00e091), the dongle will itself reply that it has the same vendor
- * ID, and it will respond to at least one vendor specific command.
- *
- * - In autonomous mode, the dongle is known to attempt wakeup if it receives
- * <User Control Pressed> ["Power On"], ["Power] or ["Power Toggle"], or if it
- * receives <Set Stream Path> with its own physical address. It also does this
- * if it receives <Vendor Specific Command> [0x03 0x00] from an LG TV.
