scsi: ufs: host: mediatek: Set IRQ affinity policy for MCQ mode

Set the IRQ affinity for MCQ mode to improve performance. Specifically,
it migrates the IRQ from CPU0 to CPU3 to enhance IRQ handling efficiency.

Setting IRQ affinity directly from the kernel allows the configuration to
take effect earlier, and provides greater security and consistency,
especially important for systems with strict performanceor real-time
requirements.
