broadcom/compiler: stop moving UBO loads before NIR scheduling

Browse source 
This doesn't have any significant impact shader-db stats and would
reduce our capacity to hide latency from the loads, so it is probably
undesirable:

total instructions in shared programs: 12663189 -> 12663186 (<.01%)
instructions in affected programs: 4222 -> 4219 (-0.07%)
helped: 9
HURT: 4

total uniforms in shared programs: 3711624 -> 3711629 (<.01%)
uniforms in affected programs: 186 -> 191 (2.69%)
helped: 0
HURT: 2

total max-temps in shared programs: 2138822 -> 2138857 (<.01%)
max-temps in affected programs: 569 -> 604 (6.15%)
helped: 1
HURT: 9
