DMAC supports. This will be 4 for SH7750/SH7751/Sh7750S/SH7091 and 8 for the
SH7750R/SH7751R/SH7760, 12 for the SH7723/SH7780/SH7785/SH7724, default is 6.
-config NR_DMA_CHANNELS_BOOL

- bool "Override default number of maximum DMA channels"
- help
- This allows you to forcibly update the maximum number of supported
- DMA channels for a given board. If this is unset, this will default
- to the number of channels that the on-chip DMAC has.

- default NR_ONCHIP_DMA_CHANNELS
- help
- This allows you to specify the maximum number of DMA channels to
- support. Setting this to a higher value allows for cascading DMACs
- with additional channels.
