hwrng: bcm2835: fix MODULE_LICENSE tag

The MODULE_LICENSE macro invocation must use either "GPL" or "GPL v2",
but not "GPLv2" in order to be detected by the module loader.

This fixes the allmodconfig build error:

FATAL: modpost: GPL-incompatible module bcm2835-rng.ko uses GPL-only symbol 'platform_driver_unregister'
