[AMDGPU] Remove s_delay_alu for VALU->SGPR->SALU (#127212)
We have a VALU->SGPR->SALU (VALU writing to SGPR and SALU reading from
it). When VALU is issued, it increments internal counter VA_SDST used to
track use of this SGPR. SALU will not issue until VA_SDST is zero, that
is when VALU is finished writing. Therefore, delays added by s_delay_alu
are not needed in this situation.
