soc/amd/picasso: fix host bridge bus numbers
The host bridge's resources covering bus numbers assumed 256 buses were being decoded. However, MMCONFIG was only covering 64 buses. This results in Linux complaining: acpi PNP0A08:00: [Firmware Info]: MMCONFIG for domain 0000 [bus 00-3f] only partially covers this bridge When retrieving the host bridge's resources fix up the bus numbers to utilize MMCONF_BUS_NUMBER Kconfig. I couldn't keep IASL from complaining when trying to do this statically.
