soc/qualcomm/sc7280: Add API to differentiate PRO and NON_PRO SKUs 

The API socinfo_pro_part() returns 1 for Pro and 0 for NON_PRO SKUs. To
reduce the binary footprint for chipinfo structure, change its members
range from uint32_t to uint16_t. Add helper functions for reading and
matching jtagid. Modified socinfo_modem_supported() API to utilize
helper functions.

BUG=b:248187555
TEST=Validate boards are detected correctly on PRO and NON_PRO SKUs
