Karthikeyan Ramasubramanian 0f718312f1 soc/intel/common: Add SOC specific function to get XHCI USB info
It feels appropriate to define SoC specific XHCI USB info in SoC
specific XHCI source file and an API to get that information instead of
defining it in elog source file. This will help in other situations
where the information is required.

BUG=None
BRANCH=None
TEST=Boot to ChromeOS.
