usb: musb_hdrc build fixes

Minor musb_hdrc updates:

  - so it'll build on DaVinci, given relevant platform updates;
      * remove support for an un-shipped OTG prototype
      * rely on gpiolib framework conversion for the I2C GPIOs
      * the <asm/arch/hdrc_cnf.h> mechanism has been removed

  - catch comments up to the recent removal of the per-SOC header
    with the silicon configuration data;

  - and remove two inappropriate "inline" declarations which
    just bloat host side code.

There are still some more <asm/arch/XYZ.h> ==> <mach/XYZ.h>
changes needed in this driver, catching up to the relocation
of most of the include/asm-arm/arch-* contents.
