The koelsch_add_standard_devices() function calls clk_get() but then fails
to check that it returns an error pointer instead of NULL on failure.
This was added by f31239ef ("ARM: shmobile: koelsch-reference:
Instantiate clkdevs for SCIF and CMT") in Simon Horman's
renesas-boards2-for-v3.14 tag.
The issue is not serious as it does not cause a crash and seems to not be
actually causing any issues now the other clock bugs have been fixed.

R-Car H2 has many DMACs
(ex SYS-DMAC, 2D-DMAC, Audio-DMAC, USB-DMAC etc)
and, these DMAEngine needs DMA slave IDs to use it.
This patch adds new DMA slave ID list for r8a7790.
There, common part has RCAR_DMA_xxx prefix,
and Audio DMAC part has AUDIO_DMAC_SLAVE_xxx prefix.
Audio DMAC can be controlled via sh-dma-engine

When enabling a module clock by clearing its bit in the MSTP control
register, the CPG requires waiting for the status register to signal
that the clock has started. Failure to do so will result in returning
from the clk_enable() call with the clock potentially still disabled,
leading to various race conditions and difficult to debug errors.
Enable status wait for all MSTP clocks on the r8a7791.
