77c1458d13 ppc/85xx: PIO Support for FSL eSDHC Controller Driver

So PIO Mode has been introduced to do data transfer using CPU.

ab467c512e fsl_esdhc: Only modify the field we are changing in WML
When we set the read or write watermark in WML we should maintain the
rest of the register as is, rather than using some hard coded value.

48bb3bb5ac fsl_esdhc: Add function to reset the eSDHC controller
To support multiple block read command we must set abort or use auto
CMD12.  If we booted from eSDHC controller neither of these are used
and thus we need to reset the controller to allow multiple block read
to function.

cc4d122658 fsl_esdhc: Always stop clock before changing frequency
We need to stop the clocks on 83xx/85xx as well as imx.  No need to make
this code conditional to just imx.

c67bee1460 fsl_esdhc: add support for mx51 processor
The esdhc controller in the mx51 processor is quite
the same as the one in some powerpc processors
(MPC83xx, MPC85xx). This patches adapts the driver
to support the arm mx51.

b33433a63f fsl_esdhc: Add device tree fixups
This patch implements fdt_fixup_esdhc() function that is used to fixup
the device tree.

The function adds status = "disabled" propery if esdhc pins muxed away,
otherwise it fixups clock-frequency for esdhc nodes.
