Subject: [PATCH] powerpc: edac: Fix build error

Fix the following build error:

drivers/edac/ppc4xx_edac.c: In function 'mfsdram':
drivers/edac/ppc4xx_edac.c:249: error: implicit declaration of function
'__mfdcri'
drivers/edac/ppc4xx_edac.c: In function 'mtsdram':
drivers/edac/ppc4xx_edac.c:266: error: implicit declaration of function
'__mtdcri'
drivers/edac/ppc4xx_edac.c:269: warning: 'return' with a value, in function
returning void
drivers/edac/ppc4xx_edac.c: In function 'ppc4xx_edac_init_csrows':
drivers/edac/ppc4xx_edac.c:924: warning: initialization from incompatible
pointer type
drivers/edac/ppc4xx_edac.c:977: error: request for member 'dimm' in something
not a structure or union
drivers/edac/ppc4xx_edac.c: In function 'ppc4xx_edac_map_dcrs':
drivers/edac/ppc4xx_edac.c:1209: warning: passing argument 1 of 'dcr_map_mmio'
discards qualifiers from pointer target type

This driver depends on PPC_DCR_NATIVE to be set for the relevant headers to be
included. Also if PPC_DCR_MMIO=n the build fails. So make PPC_DCR depend on both
these options.

This is compile tested only.
