pci: implement sending firmware image over p2a

Implement sending firmware image over p2a via the aspeed-p2a-ctrl
driver.

Test configuration:
# Image is static, uses the PCI bridge, and requires the ASPEED
# PCI-to-AHB hardware implementation.
EXTRA_OECONF_append_quanta-q71l = " --enable-static-layout"
EXTRA_OECONF_append_quanta-q71l = " --enable-pci-bridge"
EXTRA_OECONF_append_quanta-q71l = " --enable-aspeed-p2a"
EXTRA_OECONF_append_quanta-q71l = " MAPPED_ADDRESS=0x47FF0000"

Tested: Verified via md5sum the image-bmc file sent from the host via
this tool matches the hash of /run/initramfs/bmc-image.  This code can
be used to send any file down, but was only tested with a "static"
layout build.
