Subject: [PATCH] arm64: kconfig: Make STRICT_KERNEL_RWX visable.

Make "STRICT_KERNEL_RWX" visable to menuconfig on arm64 platform.

I can not set breakpoints when using kgdb/kdb on arm64, the document
says "STRICT_KERNEL_RWX" should be "n", but it's not visable in
menuconfig and the default value is "y".

kgdb/kdb doc: https://docs.kernel.org/process/debugging/kgdb.html
