libpayload/arch/x86: Introduce pacc pointer in sysinfo_t struct
Currently, the PCI bus gets scanned multiple times for various reasons
(e.g. to read the device class). Therefore, and in preparation to
CB:46416, introduce the pacc pointer in the sysinfo_t struct and scan
the PCI bus while gathering system information.
