When CMPC885 board is used for MIAE device, SCC2 SCC3 and SMC2
are used for serial lines. Therefore only SCC4 is available for
handling the TDM line.

In order to use SCC4 in QMC mode without loosing SMC2, SMC2
must be relocated.

Activate SMC relocation and relocate SMC2 at offset 0x1fc0 which
is unused.
