ASoC: Intel: cht_bsw_rt5645: Cleanup codec_name handling 
4 fixes / cleanups to the rt5645 mc driver's codec_name handling:

1. In the for loop looking for the dai_index for the codec, replace
card->dai_link[i] with cht_dailink[i]. The for loop already uses
ARRAY_SIZE(cht_dailink) as bound and card->dai_link is just a pointer to
cht_dailink using card->dai_link only obfuscates that cht_dailink is being
modified directly rather then say a copy of cht_dailink. Using
cht_dailink[i] also makes the code consistent with other machine drivers.

2. Don't set cht_dailink[dai_index].codecs->name in the for loop,
this immediately gets overridden using acpi_dev_name(adev) directly
below the loop.

3. Add a missing break to the loop.

4. Remove the now no longer used (only set, never read) codec_name field
from struct cht_mc_private.
