ARM: OMAP: 24xx pinmux updates

Add some OMAP 24xx pin mux declarations to support:

 - TUSB 6010 EVM (on H4)
 - All three full speed USB ports
 - GPIOs used with USB0 on Apollon and H4

For OMAP2, issue MUX_WARNINGS and debug messages correctly; and make the
message look more like the OMAP1 message.
