This patch makes locking in visorchannel_signalempty statically
deterministic.
As a result this patch fixes the sparse warning:
Context imbalance in 'visorchannel_signalempty' - different lock
contexts for basic block.

The logic of the locking code doesn't change but the layout of the
original code is "frowned upon"
according to mails on sparse context checking.
Refactoring removes the warning and makes the code more readable.

I've left out the downstream HDMI audio driver from the "to be
imported" section, as we'll want to handle it natively in vc4.  The
downstream kernel will likely continue to use that driver for a while
due to using the interim "vc4 firmware KMS" mode while vc4 gets its
featureset (such as HDMI audio!) completed.

I've also left out VC-CMA, which appears to be about having Linux
manage a CMA area that the firmware gets to make allocations out of.
I'm not clear on if this is useful (the firmware's need for memory
drops massively with vc4 present, and may drop even more depending on
how we resolve dmabuf handling for camera and video decode)

After a recent bugfix, we get a warning about the use of an uninitialized
variable:

drivers/staging/lustre/lnet/libcfs/linux/linux-cpu.c:833:7: error: 'str' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This part of the function used to not do anything as we would reassign
the 'str' pointer to something else right away, but now we pass an
uninitialized pointer into 'strchr', which can cause a kernel page fault
or worse.
