And use it inside struct fb_info. This struct has the advantage
that the supported modes can be passed around in a single pointer.

the check is wrong as when the clock rate is correctly set
the function will return 0.

MXS specific devices have some common infrastructure in the kernel
known as STMP devices. We have the same in barebox, but with a
mxs_ prefix instead of a stmp_ prefix. As some STMP devices are
also found on i.MX6 move the common infrastructure out of MXS
specific files and use the stmp_ prefix.
This is done in preparation for i.MX6 NAND support.

Since the info is device specific and not driver specific, attach
the callback to the device. This makes it possible to have a info
callback for a device which does not have a driver attached.

To allow for some generic io accessors introduce io.h and use
this instead of asm/io.h throughout the tree.

Video controller of STM allow to control the reset bit of an external
LCD controller. When reset_lcd is set, CTRL1_RESET bit is used to
enable and disable LCD.
Handle USE_LCD_RESET as a flag in imx_fb_platformdata.

When describing an new video interface, it is now possible to select
the bit per pixel. If nothing is chosen 16bpp is selected by default.
