Subject: [RFC PATCH] arm64: dts: rockchip: fix dmas dma-names for rk3308 i2s node

One of the current rk3308 'i2s' nodes has a different dma layout
with only 1 item. Table 9-2 DMAC1 Request Mapping Table shows that
there 2 dma sources available, so fix the dmas and dma-names
for the rk3308 'i2s' node.

10 I2S/PCM_2CH_1 tx High level
11 I2S/PCM_2CH_1 rx High level
