[PATCH] fbdev/sh7760fb: allow modular build

[Randy Dunlap]

There is no reason to prohibit sh7760fb from being built as a
loadable module as suggested by Geert, so change the config symbol
from bool to tristate to allow that and change the FB dependency as
needed.

Fixes: f75f71b2c418 ("fbdev/sh7760fb: Depend on FB=y")
