chipset_enable.c: Use PCI_ACCESS_ECAM to access pci register

In the latest pciutils(v3.13.0), it supports accessing pci registers
by ecam. This patch uses libpci version check to decide whether
flashrom calls libpci and use 0xcf8/0xcfc or ecam to access pci
registers.

BUG=b:359813524
TEST=with libpci >= 3.13.0, flashrom is working with ECAM access
