AMD K8 and AMDFAM10, GFXUMA: drop use of uma_memory_base
The code in rs690 or rs780 is always used with K8 or AMDFAM10
northbridge. Without GFXUMA, both of these set the same static value
indirectly using the variable uma_memory_base.
Make the register setting with immediate value, to remove the obscure
use of variable uma_memory_base.
