[PATCH] arm64: kaslr: fix ARM64_MODULE_PLTS dependency

[Li Bin]

There is a bug that when RANDOMIZE_BASE enabled and
RANDOMIZE_MODULE_REGION_FULL disabled, and assume that there are
many modules, and module space is not enabled, module_alloc code
now will alloc space in vmalloc space, and the patch
"fe88a4 arm64: kaslr: keep modules close to the kernel when
DYNAMIC_FTRACE=y" will be invalid.

In fact, we only need plt when RANDOMIZE_MODULE_REGION_FULL enabled,
so fix the dependency, that only RANDOMIZE_MODULE_REGION_FULL select
ARM64_MODULE_PLTS.
