soc/amd/stoneyridge/acpi/sb_pci0_fch: report correct number of PCI buses 

This ports commit 8c28e51a16 ("soc/amd/picasso: fix host bridge bus
numbers") back to Stoneyridge so that the correct number of PCI buses
gets reported from PCI0's _CRS method. The MCFG ACPI table already had
the correct last bus number.
