security/keys: make big_key.c explicitly non-modular

Browse Source 
The Kconfig currently controlling compilation of this code is:

config BIG_KEYS
        bool "Large payload keys"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We also delete the MODULE_LICENSE tag since all that information
is already contained at the top of the file in the comments.
