media: Kconfig: move comment to siano include

Showing this comment without showing the Siano mmc option
is very weird! Place the option together, and make it
visible only when showing Siano configuration.

media: Kconfig files: use the right help coding style

Checkpatch wants to use 'help' instead of '---help---':

WARNING: prefer 'help' over '---help---' for new help texts

Let's change it globally at the media subsystem, as otherwise people
would keep using the old way.

[media] siano: fix Kconfig dependencies

The USB and MMC front-ends to the siano driver both only make
sense when combined with the SMS_SIANO_MDTV driver. That driver
already requires RC_CORE to not be a module, so we also need
to add that dependency here.

[media] siano: allow compiling it without RC support

Remote controller support should be optional on all drivers.

Make it optional at Siano's driver.

[media] siano: break it into common, mmc and usb

siano is, in fact, 2 drivers: one for MMC and one for USB, plus
a common bus-independent code. Break it accordingly.
