pci-arbiter: Use libpciaccess instead of embedding it

This patch removes all embedded pciaccess code from the arbiter
and instead uses the external pciaccess library.

* pci-arbiter/Makefile:
        * Remove pci_access.c and x86_pci.c from the sources.
* pci-arbiter/func_files.c:
        * io_config_file: Use a harcoded PCI config size.
        * read_rom_file:
                Grab the full rom first, then return the
                requested amount.
* pci-arbiter/main.c:
        * main: Call create_fs_tree() w/o pci_sys.
                Since it's not part of the translator anymore.
* pci-arbiter/netfs_impl.c:
        * netfs_attempt_read:
		Send pci_device_cfg_read() as the read op.
        * netfs_attempt_write:
                Send pci_device_cfg_write() as the write op.
* pci-arbiter/pci-ops.c:
        * S_pci_conf_read: Call libpciaccess' pci_device_cfg_read().
        * S_pci_conf_write: Call libpciaccess' pci_device_cfg_write().
        * S_pci_get_dev_rom:
		Set rom.base_addr to zero for the moment, until
		  libpciaccess esposes it properly.
* pci-arbiter/pci_access.c: Deleted
* pci-arbiter/pci_access.h: Deleted
* pci-arbiter/pcifs.c:
        * create_fs_tree:
                Remove the pci_sys parameter.
		Use libpciaccess' iterator.
		Use a hardcoded config space size.
* pci-arbiter/pcifs.h: Definitions for changes in pcifs.c.
* pci-arbiter/x86_pci.c: Deleted.
* pci-arbiter/x86_pci.h: Deleted.
