The KS8851 config was added like 10years ago and is used on some omap4 platforms,
it does select MICREL_PHY.

 From other side, *some* am57x, am437 platforms uses MICREL PHYs with no dependency from KS8851.

The omap2plus_defconfig is also used as base for custom configs and first thing people are doing -
remove not needed options. As result, removal of KS8851 plus this patch will immediately
cause MICREL_PHY=n and so breakage on existing and custom platforms.

I do not see how it can be resolved by using Kconfig changes within much-omap2.

So, sry, but NACK for this patch as it is.

if some Kconfig dependencies need to be sorted out - probably the best way might be
to get rid of select MICREL_PHY in KS8851/KS8851_MLL.
