Subject: [PATCH] fix(bl1): add missing spinlock dependency

The spinlock functions from `spinlock.S` are used by `errata_report.c`,
which is pulled into BL1. In a normal build it appears that this
function call undergoes dead code elimination so the link error is not
reported, but when compiled with LTO enabled the linker reports an
undefined reference.
