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.
