AMD AGESA cimx/sb700: Drop APIC_ID_OFFSET and MAX_PHYSICAL_CPUS
Following boards use cimx/sb700: amd/dinar supermicro/h8qgi supermicro/h8scm tyan/s8226 Only amd/dinar had APIC_ID_OFFSET defined, thus all had 0x0. There was a nonsense preprocessor directive (MAX_CPUS * MAX_PHYSICAL_CPUS >= 1). Except for tyan, (MAX_CPUS * MAX_PHYSICAL_CPUS) % 256 == 0. Together with documented 4-bit restriction for APIC ID field, this APIC ID programming matches with MP tables and ACPI tables. I believe this would also fix cases of cimx/sb700 with MAX_CPUS<16, which we do not have in the tree.
