mfd: Add HTCPLD driver
This change introduces a driver for the HTC PLD chip found
on some smartphones, such as the HTC Wizard and HTC Herald.
It works through the I2C bus and acts as a GPIO extender.
Specifically:
* it can have several sub-devices, each with its own I2C
address
* Each sub-device provides 8 output and 8 input pins
* The chip attaches to one GPIO to signal when any of the
input GPIOs change -- at which point all chips must be
scanned for changes
This driver implements the GPIOs throught the kernel's
GPIO and IRQ framework. This allows any GPIO-servicing
drivers to operate on htcpld pins, such as the gpio-keys
and gpio-leds drivers.
