[U-Boot] [PATCH 38/42] board: freescale: common: diu_ch7301: support dm_i2c_* API

[Biwen Li]

This supports dm_i2c_* API to
fix compilation error as follows:
	- board/freescale/common/built-in.o: In function `diu_set_dvi_encoder:
	  board/freescale/common/diu_ch7301.c:54: undefined reference to
	  `i2c_write'
	  board/freescale/common/diu_ch7301.c:61: undefined reference to
	  `i2c_write'
	  board/freescale/common/diu_ch7301.c:70: undefined reference to
	  `i2c_write'
	  board/freescale/common/diu_ch7301.c:80: undefined reference to
	  `i2c_write'
	  board/freescale/common/diu_ch7301.c:87: undefined reference to
	  `i2c_write'
	  board/freescale/common/diu_ch7301.c:102: more undefined
	  references to `i2c_write' follow
