When the lp5860 is compiled as module, the lp5860_device_init/remove
functions must be exported or the spi-specific module can not use these
functions and the compilation will fail.

Add the needed EXPORT_SYMBOL_GPL calls and while at it the
MODULE_LICENSE and _DESCRIPTION for the lp5860-core module.
