svn commit: r367538 - head/sys/arm64/arm64

Log:
  arm64: bs_sr_<N> take II
  
  In r367327 generic_bs_sr_<n> were derived from mips.  Given we are calling
  generic_bs_w_<n> and no write directly, we do not have to do the address
  calculations ourselves as eneric_bs_w_<n> will do a str val [bsh, offset].
  All we actually have to do is increment offset.
