Following patch added the omap_type() functionality for omap4
737daa03: omap4: Fix omap_type() for omap4
However the omap_type() function would not work as:
1) the base address for CONTROL_STATUS register is wrong
So insted of using omap_ctrl_readl that has a different base offset,
use a correct offset using omap_readl
2) "Not yet supported" check for omap4 needs to be removed
Verified on OMAP4 SDP board

V1: had broken mmc support
V2: No mmc break; use omap_readl to get to the right register
