powerpc/8xx: Remove macro that checks kernel address
The macro to check if an address is a kernel address or not is not used anymore in DTLBmiss handler. It is used in ITLB miss handler and in DTLB error handler. DTLB error handler is not a hot path, it doesn't need such optimisation. In order to simplify a following patch which will rework ITLB miss handler, we remove the macros and reintroduce them inside the handler.
