The build files for drivers/gpio has some wording and comments about the directory being reserved exclusively for GPIO expanders (according to the gpio.txt file these are on external busses) and this has been false for some time. We already have PL061 and Xilinx drivers which are in silicon and now I'm moving more silicon drivers here, so delete this and reword it a bit.

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.

Add support for the GPIO pins on the WM831x. No direct support is currently supplied for configuring non-gpiolib functionality such as pull configuration and alternate functions, soft configuration of these will be provided in a future patch. Currently use of these pins as interrupts is not supported due to the ongoing issues with generic irq not support interrupt controllers on interrupt driven buses.

This patch adds functionality to the gpio-lib subsystem to make it possible to enable the gpio-lib code even if the architecture code didn't request to get it built in. The archtitecture code does still need to implement the gpiolib accessor functions in its asm/gpio.h file. This patch adds the implementations for x86 and PPC. With these changes it is possible to run generic GPIO expansion cards on every architecture that implements the trivial wrapper functions. Support for more architectures can easily be added.
