powerpc/kasan: Fix boot failure with RELOCATABLE && FSL_BOOKE
When enabling CONFIG_RELOCATABLE and CONFIG_KASAN on FSL_BOOKE,
the kernel doesn't boot.
relocate_init() requires KASAN early shadow area to be set up because
it needs access to the device tree through generic functions.
Call kasan_early_init() before calling relocate_init()
