[PATCH] i2c: Kconfig: Allow I2C_MXS to be selected by MX23

[PATCH] i2c: Kconfig: Allow I2C_MXS to be selected by MX23

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam-KZfg59tc24xl57MIdRCFDg@public.gmane.org>

With the recent DMA support addition to the i2c-mxs driver, it is now possible 
to also run it on mx23, so update the Kconfig entry accordingly.

Won't i.MX23/i.MX28 instead of MXS be less confusing? Either way:

I kept MXS to let it consistent with other Kconfig files, such as
spi-mxs, mmcmxs, etc.

Thanks,

I don't have the I2C connector board for mx23-olinuxino, but I have
been helping Fadil Berisha (on Cc) to get I2C to work on mx23.

He managed to get I2C working on his mx23 board and posted the results at:
https://www.olimex.com/forum/index.php?topic=283.msg1086#msg1086

He has already sent the dts patches to the ARM kernel list.
