Icenowy Zheng e0eb9bc602 pvr: set has_usc_alu_roundingmode_rne for all B-series Rogue cores 
All B-series Rogue cores seem to have USC rounding mode as RTE instead
of RTZ.

Set the has_usc_alu_roundingmode_rne feature flag for them (currently
only BXS-4-64 has it set).

Verified via testing on BXM-4-64 (36.52.104.182) by fixing CTS tests
dEQP-VK.spirv_assembly.instruction.*.float_controls.fp32.input_args.* ,
and via proprietary driver vulkaninfo result on BXE-2-32 (36.29.52.182),
BXE-4-32 (36.50.54.182) and BXM-4-64 (36.56.104.183) (checking
shaderRoundingModeRT?Float32 properties).
