ea05e8b4ec [media] rc: sunxi-cir: support module autoloading
MODULE_DEVICE_TABLE() is missing, so the module isn't auto-loading on
systems supporting infrared. This commit adds the missing line so it
works out of the box when built as a module and running on a sunxi
system with an infrared receiver.

768acf46e1 [media] rc: sunxi-cir: Initialize the spinlock properly
The driver allocates the spinlock but fails to initialize it correctly.
The kernel reports a BUG indicating bad spinlock magic when spinlock
debugging is enabled.

Call spin_lock_init() on it to initialize it correctly.

Fixes: b4e3e59fb5 ("[media] rc: add sunxi-ir driver")

a4bca4c7ad [media] rc: sunxi-cir: Add support for the larger fifo found on sun5i and sun6i
Add support for the larger fifo found on sun5i and sun6i, having a separate
compatible for the ir found on sun5i & sun6i also is useful if we ever want
to add ir transmit support, because the sun5i & sun6i version do not have
transmit support.

Note this commits also adds checking for the end-of-packet interrupt flag
(which was already enabled), as the fifo-data-available interrupt flag only
gets set when the trigger-level is exceeded. So far we've been getting away
with not doing this because of the low trigger-level, but this is something
which we should have done since day one.

On sun6i the cir block is attached to the reset controller, add support
for de-asserting the reset if a reset controller is specified in dt.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

c5540fbb9d [media] rc-core: remove protocol arrays
The basic API of rc-core used to be:

	dev = rc_allocate_device();
	dev->x = a;
	dev->y = b;
	dev->z = c;
	rc_register_device();

which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:

	dev = rc_allocate_device();
	dev->x = a;
	rc_set_allowed_protocols(dev, RC_BIT_X);
	dev->z = c;
	rc_register_device();

There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).
