powerpc/kasan: Fix boot failure with RELOCATABLE && FSL_BOOKE
commit5.4-rM2-2.2.x-imx-squashed71eb40fc53
upstream. 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() Reported-by: Lexi Shao <shaolexi@huawei.com> Fixes:2edb16efc8
