dmaengine: sh: rz-dmac: Drop unnecessary local_irq_save() call

rz_dmac_enable_hw() calls local_irq_save()/local_irq_restore(), but
this is not needed because the callers of rz_dmac_enable_hw() already
protect the critical section using
spin_lock_irqsave()/spin_lock_irqrestore().

Remove the local_irq_save()/local_irq_restore() calls.
