dt-bindings: clock: ast2600: Add I3C and MAC reset definitions

Add reset definitions of AST2600 I3C and MAC controllers. In the case of
the I3C reset, since there is no reset-line hardware available for
`ASPEED_RESET_I3C_DMA`, a new macro `ASPEED_RESET_I3C` with the same ID
is introduced to provide a more accurate representation of the hardware.
The old macro `ASPEED_RESET_I3C_DMA` is kept to provide backward
compatibility.
