[PATCH 01/13] video: sh_mobile_lcdcfb depends on meram

[Peter Griffin]

From: Arnd Bergmann <arnd@xxxxxxxx>

The sh_mobile_lcdcfb driver calls interfaces provided
by the corresponding "meram" helper. This fails if meram
is a module but lcdcfb is built-in.

To work around it, this uses special Kconfig magic to
only allow lcdcfb to be built if
a) both are modules,
b) meram is built-in, or
c) meram is disabled and the helpers stubbed out

Changing meram from 'y' to 'm' now forces clcd to
be a module as well, which seems to be the desired
behavior.
