powerpc/32: Set an IBAT covering up to _einittext during init
Always set an IBAT covering up to _einittext during init because when
CONFIG_MODULES is not selected there is no reason to have an exception
handler for kernel instruction TLB misses.
It implies DBAT and IBAT are now totaly independent, IBATs are set
by setibat() and DBAT by setbat().
This allows to revert commit 9bb162fa26ed ("powerpc/603: Fix
boot failure with DEBUG_PAGEALLOC and KFENCE")
