Provide an option to use PCI_ACCESS_ECAM to access pci register

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

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