Subject: [PATCH] powerpc: Remove cpm_dp...() macros

Since commit d3c511ac1d72 ("powerpc/cpm: Remove
!CONFIG_PPC_CPM_NEW_BINDING code") cpm_dp...() macros have no added
value anymore.

Last user of those macros were fixed by commit 5e6cb39a256d ("net:
fs_enet: Use cpm_muram_xxx() functions instead of cpm_dpxxx() macros")

Remove them.
