Subject: [PATCH 220/752] ARM/dts: am33xx: mcasp: Add new dma register
 location to reg-property

This patch adds an optional address range to reg property. The range
describes the register location for DMA controller on am33xx. The both
address ranges are named accordingly in the reg-names property.
