soc/cavium/cn81xx/Kconfig: specify ECAM_MMCONF_BUS_NUMBER

The Cavium CN82xx SoC selects ECAM_MMCONF_SUPPORT, but doesn't set a
value for ECAM_MMCONF_BUS_NUMBER which results in it defaulting to 0
which is wrong. Unsure what the correct value would be here, so set it
to the maximum of 256 buses that a system with a single PCI segment
group can have and add a TODO. This will be at least less wrong than the
previous solution.
