[SYCL][CUDA] Updated tf32 device code check comment. (#7353)

Checks for equivalence between 
a) __hmma_m16n16k16_ld_c_f32 and __mma_tf32_m16n16k8_ld_c
b) __hmma_m16n16k16_st_c_f32 and __mma_m16n16k8_st_c_f32
clang builtins have been made for all archs supported by the latest
driver. I've updated the comment accordingly.

 // NOTE: Technically the 'wrong' ptx instruction is called by
 // joint_matrix_load/joint_matrix_store in this case: notice that the load and
 // store instructions use shape m16n16k16, rather than the correct shape
 // m16n16k8. The 'wrong' ptx instruction is used because it returns the correct
-// SASS instructions for all existing supported sm versions: sm_80 and sm_86.
-// The reason for this ptx instruction redundancy is due to the ptx naming
-// convention for the mnk shape triple; however we cannot in principle a priori
-// know that future sm versions will behave in the same way and that this
-// redundancy will continue as future architecture is released. This should be
-// validated before supporting any sm versions beyond sm_86. The reason that we
-// choose to use the m16n16k16 instruction is that it allows the significant
-// advantage of being able to use a portable interface across Intel and Nvidia
