When CONFIG_MCF_EDMA is set (due to COMPILE_TEST, not due to
CONFIG_M5441x), coldfire/device.c has compile errors due to
missing MCFEDMA_* symbols. In the .config file that was provided,
CONFIG_M5206=y, not CONFIG_M5441x, so <asm/m5441xsim.h> is not
included in coldfire/device.c.

Only build the MCF_EDMA code in coldfire/device.c if the MCFEDMA_*
hardware macros are defined.

Fixes these build errors:

../arch/m68k/coldfire/device.c:512:35: error: 'MCFEDMA_BASE' undeclared here (not in a function); did you mean 'MCFDMA_BASE1'?

  513 |                 .end            = MCFEDMA_BASE + MCFEDMA_SIZE - 1,
