powerpc/44x: Fix mask and shift to zero bug 



My static checker complains that 0x00001800 >> 13 is zero. Looking at
the context, it seems like a copy and paste bug from the line below
and probably 0x3 << 13 or 0x00006000 was intended.

Fixes: 2af59f7d ("[POWERPC] 4xx: Add 405GPr and 405EP support in boot wrapper")
