Since the DMA controller clocks are managed at amba bus level, the
PL330 device clocks handling has been removed from the driver in
commit 7c71b8eb("DMA: PL330: Remove redundant runtime_suspend/
resume functions")
However, this left the S5PV210 platform with only clkdev entries
linking "apb_pclk" clock conn_id to a dummy clock, rather than
to corresponding platform PL330 DMAC clock.
As a result the DMA controller is now attempted to be used on
S5PV210 with the clock disabled and the driver fails with an
error:
dma-pl330 dma-pl330.0: PERIPH_ID 0x0, PCELL_ID 0x0 !
dma-pl330: probe of dma-pl330.0 failed with error -22
dma-pl330 dma-pl330.1: PERIPH_ID 0x0, PCELL_ID 0x0 !
dma-pl330: probe of dma-pl330.1 failed with error -22
Fix this by adding "apb_pclk" clkdev entries for the Peripheral
DMA controllers 0/1 and removing the dummy apb_pclk clock.
