[PATCH 3/3] [media] cec: add RC_CORE dependency

[Arnd Bergmann <arnd@arndb.de>]

We cannot build the cec driver when the RC core is a module
and cec is built-in:

drivers/staging/built-in.o: In function `cec_allocate_adapter':
:(.text+0x134): undefined reference to `rc_allocate_device'
drivers/staging/built-in.o: In function `cec_register_adapter':
:(.text+0x304): undefined reference to `rc_register_device'

This adds an explicit dependency to avoid this case. We still
allow building when CONFIG_RC_CORE is disabled completely,
as the driver has checks for this case itself.
