When building MHI as a module, missing MODULE_LICENSE() warnings

I would expect you only need to add the MODULE_* once per module, in
which case main.c is probably the only place that needs it.

Hi Jeff,

I thought so too. This is to fix below warnings seen when building MHI as a MODULE:

WARNING: modpost: missing MODULE_LICENSE() in drivers/bus/mhi/core/main.o
WARNING: modpost: missing MODULE_LICENSE() in drivers/bus/mhi/core/pm.o
WARNING: modpost: missing MODULE_LICENSE() in drivers/bus/mhi/core/boot.o

We've only had those in init.c so far.

Thanks,
Bhaumik
