Now that ARM64 also has a fncpy() implementation, allow selection SRAM_EXEC for ARM64 as well.

As stated in another thread [1], NAK to this patch. Currently there are no users of this interface that we wish to enable for arm64, and this is liable to be abused to add platform-specific stuff that we expect to live in PSCI or other secure FW. Until we have a user that does not fall into that bucket, I see no reason to enable this for arm64. Thanks, Mark. [1] http://lists.infradead.org/pipermail/linux-arm-kernel/2017-June/516161.html
