phaser: add internal PUs for unused pins to prevent leakage current.
This CL adds internal PUs for unused pins on phaser in gpio.inc to
prevent leakage current since default GPIO functionality. These unused
pins which need internal PUs/PDs usage will be added in the section
3.5.1 in next version of the datasheet.
