dmaengine: dw-edma: Fix HDMA channel status register access

Browse Source 
GET_CH_32() takes the direction before the channel ID, but
dw_hdma_v0_core_ch_status() passed them in the opposite order. This can
make the status callback read another HDMA channel status register.

Use the same argument order as the other HDMA register accesses.
