An existing macro, ASPEED_RESET_I3C_DMA, was removed in V1. However,
considering that this macro may be used somewhere, I have decided to
add it back in V2. I will ensure to include the changelog in V3.

This is the macro I added back in V2. There is no reset-line hardware
available for `ASPEED_RESET_I3C_DMA`, so I have added a new macro to
provide a better representation of the hardware design. I will include
the explanation in the commit message of V3.
