fix system config overwrite @ MPC834x and MPC8313
During 83xx setup the "System I/O configuration register high" gets
overwritten with user defined value if CFG_SICRH is defined.
Regarding to the MPC834x manual (Table 5-28 reve.1) bits 28+29 of SICRH
must keep their reset value regardless of configuration.
On my board (using RGMII) those bits are set after reset - yet it's
unclear where they come from.
The patch keeps both bits on MPC834x and MPC8313.
