arm64: Only select ARM64_MODULE_PLTS if MODULES=y
Selecting CONFIG_RANDOMIZE_BASE=y and CONFIG_MODULES=n fails to build
the module PLTs support:
CC arch/arm64/kernel/module-plts.o
/work/Linux/linux-2.6-aarch64/arch/arm64/kernel/module-plts.c: In function ‘module_emit_plt_entry’:
/work/Linux/linux-2.6-aarch64/arch/arm64/kernel/module-plts.c:32:49: error: dereferencing pointer to incomplete type ‘struct module’
This patch selects ARM64_MODULE_PLTS conditionally only if MODULES is
enabled.
Fixes: f80fb3a3d508 ("arm64: add support for kernel ASLR")
