[PATCH 20/21] ASoC: rt5645: store eq kcontrol byte in __be

[Pierre-Louis Bossart]

From: Bard liao <yung-chuan.l...@linux.intel.com>

The eq parameters binary is stored in __be. However, it is unsigned short
in rt5645_eq_param_s{} which will cause incorrect type assignment. So add
struct rt5645_eq_param_s_be16{} to store the eq binary and convert it to
unsigned short in rt5645->eq_param.
