The GPIO function, provided by Intel Tiger Point NM10, can be accessed
through GPIO Base Address Register (GPIOBASE). The configuration on
CT-CCV6X is described as below.

0x500
The general I/O read/write function is used to access and configure the NM10.
Through the I/O read or write command, the current status of GPIO can
configure each pin to input or output.
