V4L/DVB: staging/lirc: fix non-CONFIG_MODULES build horkage

Fix when CONFIG_MODULES is not enabled:

drivers/staging/lirc/lirc_parallel.c:243: error: implicit declaration of function 'module_refcount'
drivers/staging/lirc/lirc_it87.c:150: error: implicit declaration of function 'module_refcount'
drivers/built-in.o: In function `it87_probe':
lirc_it87.c:(.text+0x4079b0): undefined reference to `init_chrdev'
lirc_it87.c:(.text+0x4079cc): undefined reference to `drop_chrdev'
drivers/built-in.o: In function `lirc_it87_exit':
lirc_it87.c:(.exit.text+0x38a5): undefined reference to `drop_chrdev'

Its a quick hack and untested beyond building, since I don't have the
hardware, but it should do the trick.
