gpiolib doesn't need to modify the names and I assume most initializers use string constants that shouldn't be modified anyhow.

The cs5535-gpio driver's get() function was returning the output value. This means that the GPIO pins would never work as an input, even if configured as an input. The driver should return the READ_BACK value, which is the sensed line value. To make that work when the direction is 'output', INPUT_ENABLE needs to be set. In addition, the driver was not disabling OUTPUT_ENABLE when the direction is set to 'input'. That would cause the GPIO to continue to drive the pin if the direction was ever set to output. This issue was noticed when attempting to use the gpiolib driver to read an external input. I had previously been using the char/cs5535-gpio driver.

This creates a CS5535/CS5536 GPIO driver which uses a gpio_chip backend (allowing GPIO users to use the generic GPIO API if desired) while also allowing architecture-specific users directly (via the cs5535_gpio_* functions). Tested on an OLPC machine. Some Leemotes also use CS5536 (with a mips cpu), which is why this is in drivers/gpio rather than arch/x86. Currently, it conflicts with older geode GPIO support; once MFGPT support is reworked to also be more generic, the older geode code will be removed.
