[AMDGPU] Restrict to VGPR only for mfma scale operands (#158117)
Restrict to VGPR only (VRegSrc_32) for mfma scale operands to workaround
a hardware design defect: For all Inline/SGPR constants, SP HW use bits
[30:23] as the scale.
TODO: We may still be able to allow Inline Constants/SGPR, with a proper
shift, to obtain a potentially better performance.
Fixes: SWDEV-548629
