[PATCH] media: sp8870: move it to staging

[Mauro Carvalho Chehab]

This driver is used only ba av7110, which is preparing for
its retirement. So, move this ancillary driver to stay together
with av7110.

Don't you need a TODO file for these moves that says what is wrong with
the driver and when it will be removed and to not send cleanups for it?

Yes, but it was added on the previous patch that moved the master driver
(av7110):

	https://lore.kernel.org/linux-media/4e7136434c68eabcdb66d25f44946ab794f4af0b.1622476959.git.mchehab+huawei@kernel.org/T/#u

The TODO is just saying:

	This driver is too old and relies on a different API.
	Drop it from Kernel on a couple of versions.

(there was a typo there, I'll fix at the next version)

Thanks,
Mauro
