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.
