If a sw_sync timeline was created by ADF (for drivers that do not implement
ops->complete_fence) we should clean it up when the ADF device is
destroyed.

Not calling rb_erase() can cause slab corruption, as the rb_first() call
after kfree() in adf_obj_destroy() can return the same node twice unless
it is erased.
This problem was reproduced by unloading a kernel module that used the
adf framework *after* a vsync event was registered. A crash would occur
in rb_first(). (Just loading and immediately unloading the module without
the vsync event worked correctly.)

Quirks specify common behaviors that vary slightly among devices, and
which ADF must account for.
The buffer padding quirk captures the way different devices fetch the
last scanline in a buffer: some devices fetch an entire line (including
padding to the pitch) while others only fetch up to the visible width.
ADF's buffer size validation now takes this quirk into account.

There are no in-tree users of adf_attachment_allow, but out-of-tree
modules want to use it. It looks like this function should be
EXPORT_SYMBOL.

Interfaces default to unplugged, so they should also default to off

Many custom formats look a lot like the standard ones, but with
different subsampling, bpp, etc. Expose and document
adf_buffer_validate()'s main body, so drivers can reuse its logic when
validating these formats.

Informational flags don't affect ADF directly but may be useful to
clients. Currently used to indicate primary and external displays.
