ARC fixes for 5.0 final

 - Fix memcpy to prevent prefetchw beyond end of buffer [Eugeniy]

 - Enable unaligned access early to prevent exceptions given newer gcc
   code gen [Eugeniy]

 - Tighten up uboot arg checking to prevent false negatives and also
   allow both jtag and bootloading to coexist w/o config option as
   needed by kernelCi folks [Eugeniy]

 - Set slab alignment to 8 for ARC to avoid the atomic64_t unalign [Alexey]

 - Disable regfile auto save on interrupts on HSDK platform due to a
   silicon issue  [Vineet]

 - Avoid HS38x boot printing crash by not reading HS48x only reg [Vineet]
