AMDGPU/SI: Change predicate to isCIOnly for 32-bit imm s_buffer_load* patterns

Summary:
This is essentially NFC, because the complex pattern used for these patterns
will fail on non-CI, but this makes the pattern consistent with other CI
smrd patterns.  It is also a performance improvement, because the pattern
will now fail earlier on non-CI.
