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.
