Move setup_uma_memory() to AMDFAM10 northbridge

Following boards had identical code:
  advansus/a785e-i
  amd/bimini_fam10
  amd/mahogany_fam10
  asus/m5a88-v
  avalue/eax-785e
  gigabyte/ma78gm
  iei/kino-780am2-fam10
  jetway/pa78vm5

Following boards had identical code:
  amd/tilapia_fam10
  asus/m4a78-em
  asus/m4a785-m
  gigabyte/ma785gm
  gigabyte/ma785gmt

In between the two, only whitespace difference.
