bus: fsl-mc: Remove deadcode

Browse Source 
fsl_mc_allocator_driver_exit() was added explicitly by
commit 1e8ac83b6caf ("bus: fsl-mc: add fsl_mc_allocator cleanup function")
but was never used.

Remove it.

fsl_mc_portal_reset() was added in 2015 by
commit 197f4d6a4a00 ("staging: fsl-mc: fsl-mc object allocator driver")
but was never used.

Remove it.

fsl_mc_portal_reset() was the only caller of dpmcp_reset().

Remove it.
