dpcm_fe_dai_startup() (= A) calls dpcm_set_fe_runtime() (= B) to setup
DPCM runtime. From *naming point of view*, it sounds like setup function
for FE.

(A)	static int dpcm_fe_dai_startup(...)
	{
		...
(B)		dpcm_set_fe_runtime(...);
		...
	}

But in dpcm_set_fe_runtime() (= B),
It  setups FE by dpcm_runtime_setup_fe() (= X),
and setups BE by dpcm_runtime_merge_xxx() (= Y).

(B)	static void dpcm_set_fe_runtime(...)
	{
		...
(X)		dpcm_runtime_setup_fe(...);

 ^		dpcm_runtime_merge_format(...);
(Y)		dpcm_runtime_merge_chan(...);
 v		dpcm_runtime_merge_rate(...);
	}

These means that the function which is called as xxx_fe_xxx()
is setups both FE and BE. This is confusable and can be hot bed for bug.

This patch renames unclear dpcm_runtime_merge_xxx() (= Y) to
more clear dpcm_runtime_setup_be_xxx().
