When setting the CCS mode, we mistakenly used wa_masked_en() to apply the workaround, which reads from the register and masks the existing value with the new one. Our intention was to write the value directly, without masking it. So far, this hasn't caused issues because we've been using a register value that only enables a single CCS engine, typically with an ID of '0'. However, in upcoming patches, we will be utilizing multiple engines, and it's crucial that we write the new value directly without any masking.
