Analog Baseband chips. The register access functions are moved
out to a separate struct abx500_ops. In this way the interface
is moved from the implementation and the sub functionality drivers
can keep their interface intact when chip infrastructure and
communication mechanisms changes. We also define the AB3550
device IDs and the AB3550 platform data struct and convert
the catenated 32bit event to an array of 3 x 8bits.

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.
