ARM: OMAP: I2C: tps65010 driver converts to gpiolib

Browse source 
Make the tps65010 driver use gpiolib to expose its GPIOs.

Note: This patch will get merged via omap tree instead of I2C
as it will cause some board updates. This has been discussed
at on the I2C list:

* struct tps65010_board - packages GPIO and LED lines
* @base: the GPIO number to assign to GPIO-1
* @outmask: bit (N-1) is set to allow GPIO-N to be used as an
* (open drain) output
* @setup: optional callback issued once the GPIOs are valid
* @teardown: optional callback issued before the GPIOs are invalidated
* @context: optional parameter passed to setup() and teardown()
*
* Board data may be used to package the GPIO (and LED) lines for use
* in by the generic GPIO and LED frameworks. The first four GPIOs
* starting at gpio_base are GPIO1..GPIO4. The next two are LED1/nPG
* and LED2 (with hardware blinking capability, not currently exposed).
*
* The @setup callback may be used with the kind of board-specific glue
* which hands the (now-valid) GPIOs to other drivers, or which puts
* devices in their initial states using these GPIOs.
