Linus Walleij 8e0285ab95 ARM/musb: omap2: Remove global GPIO numbers from TUSB6010
The TUSB6010 (MUSB) device is picking up some GPIO lines
hardcoded by number and passing on to the TUSB6010 device
when registering it.

Instead of nasty workarounds, provide a GPIO descriptor
table and then make the TUSB6010 MUSB glue driver pick up
the GPIO lines directly, convert it to an IRQ and pass down
to the MUSB driver. OMAP2 is the only system using the
TUSB6010.

Stash the GPIO descriptors in the glue layer and use
then to power up and down the TUSB6010 on-demand, instead
of using boardfile callbacks.

Since the OMAP2 boards are the only boards using the
.set_power() and .board_set_power() callbacks, we can
just delete them as the power is now handled directly
in the TUSB6010 glue code.
