mainboard/{asus/f2a85-m,amd/thatcher}: move UDELAY_LAPIC

Stefan Reinauer suggested 'select UDELAY_LAPIC' did not belong in
f2a85-m/Kconfig. It got there via copy-paste from thatcher/Kconfig
so this commit removes the 'select UDELAY_LAPIC' from both and puts
it in cpu/amd/agesa/family15tn/Kconfig

Since f2a85-m is the only Thatcher board coreboot supports right
now, this should not break any other boards.
