soc/intel/tigerlake: Add Jasper lake GPIO support

Add gpio definition for Jasper Lake gpio controller.

Also created a separate file for JSL and TGL gpio keeping common asl file.
gpio_soc_defs.h must pass correct information/macro values to asl file
for code to work.

GPIO controller includes 4 gpio community and 10 groups. Patch adds
definition for all gpio within community and groups

Updated IRQ mapping for all gpios

TEST=Check if jslrvp and tglrvp code is compiling
