soc/intel/common/gpio_defs: Enable configuring GPIO_DW2 pad register
Currently all the helpers support configuring GPIO_DW0/1 registers. In
some architectures there is an additional configuration GPIO_DW2 register
that can be used to configure debounce duration etc. Add a helper macro
to enable configuring GPIO_DW2 pad register.
BRANCH=octopus
BUG=b:117953118
TEST=Ensure that the system boots to ChromeOS. Ensure that the current
configuration is not disturbed by turning on the GPIO_DEBUG option and
verifying the debug output before and after the change.
