OMAP hwmod: convert header files with static allocations into C files

Code should be able to #include any header file without the fear that
the header file will go allocating memory.  This is a coding style
issue, similar to commit 82e9bd588563c4e22ebb55b684ebec7e310cc715.
Move the existing hwmod data from .h files to .c files.

While here, convert "omap34xx" to "omap3xxx" in the hwmod files, since
most of these structures should be reusable across all OMAP3 chips.
