ppc4xx: Cleanup of "ppc4xx: Optimize PLB4 Arbiter..." patch
This patch fixes some minor issues introduced with the patch:
ppc4xx: Optimize PLB4 Arbiter... from Prodyut Hazarika:
- Rework memory-queue and PLB arbiter optimization code, that the
local variable is not needed anymore. This removes one #ifdef.
- Use consistant spacing in ppc4xx.h header (XXX + 0x01 instead
of XXX+ 0x01). This was not introduced by Prodyut, just a
copy-paste problem.
