crypto: Kconfig - submenus for arm and arm64

Browse source 
Move ARM- and ARM64-accelerated menus into a submenu under
the Crypto API menu (paralleling all the architectures).

Make each submenu always appear if the corresponding architecture
is supported. Get rid of the ARM_CRYPTO and ARM64_CRYPTO symbols.

The "ARM Accelerated" or "ARM64 Accelerated" entry disappears from:
    General setup  --->
    Platform selection  --->
    Kernel Features  --->
    Boot options  --->
    Power management options  --->
    CPU Power Management  --->
[*] ACPI (Advanced Configuration and Power Interface) Support  --->
[*] Virtualization  --->
[*] ARM Accelerated Cryptographic Algorithms  --->
     (or)
[*] ARM64 Accelerated Cryptographic Algorithms  --->
    ...
-*- Cryptographic API  --->
    Library routines  --->
    Kernel hacking  --->

and moves into the Cryptographic API menu, which now contains:
      ...
      Accelerated Cryptographic Algorithms for CPU (arm) --->
      (or)
      Accelerated Cryptographic Algorithms for CPU (arm64) --->
[*]   Hardware crypto devices  --->
      ...
