xtensa: smp_lx200_defconfig: fix vectors clash

jcmvbkbc · jcmvbkbc · commit 306b38305c0f · 2019-01-26T02:02:13.000-08:00
Secondary CPU reset vector overlaps part of the double exception handler
code, resulting in weird crashes and hangups when running user code.
Move exception vectors one page up so that they don't clash with the
secondary CPU reset vector.
