[U-Boot] [PATCH] mpc85xx: clean up the old deep sleep framework

All the boards that support deep sleep feature are converted to deep sleep generic board interface. The old interface which support non-generic board is not used anymore. So clean it up.

I know for sure we have some patches pending. It would be helpful if you list all the dependency so I won't apply this one first. It will be a good habit for all future patches.

Hello York,
The following 3 patches, which are independent to each other, should be applied first before this one get applied. You can apply these 4 patches in the order I sent them.
1. mpc85xx/t102xrdb: convert deep sleep to generic board interface http://patchwork.ozlabs.org/patch/422189/ 2. mpc85xx/t1040qds: convert deep sleep to generic board interface http://patchwork.ozlabs.org/patch/422451/ 3. mpc85xx/t102xqds: convert deep sleep to generic board interface http://patchwork.ozlabs.org/patch/422447/
Thanks, Yuantian

Applied to u-boot-mpc85xx master branch, awaiting upstream.
