[PATCH 2/9] mmc: hsmmc_omap: include types.h and provide header inclusion guard

* Suman Anna [off-list ref] [180213 01:33]:

The hsmmc-omap platform data header file uses some u8/u16/u32 types,
so include the linux types.h header file so that it is self-contained.
The lack of this header caused some build errors while cleaning up some
other header files from various omap_hwmod data files.

While at this, also add the missing header inclusion guard.

Hi Ulf,

This patch is part of a hwmod cleanup series, and is needed before I
can do the cleanup in those files. So prefer to have this patch go
through Tony as part of the series.

No need for this, I'll post a patch that includes types.h
directly in the calling code.

Regards,

Tony
