libpci: Add PCIe ECAM access method

This is a new direct hardware access method via PCIe ECAM (Enhanced
Configuration Access Mechanism). It is available on all PCIe-compliant
hardware. Requires root privileges and access to physical memory.

ECAM mapping can be specified manually via a new ecam.addrs parameter or
can be read from ACPI MCFG table. ACPI MCFG table can be located in the
system or read from x86 BIOS memory.
