[U-Boot] [U-Boot, v2, 16/19] rockchip: Move pull-up/down enum into a common file

[Philipp Tomsich]

> At present this enum is only available to rk3288. Move it so that other
> rockchip SoCs can access it. It is needed for the SPL GPIO driver for
> rk3999 in a later patch.
> 
> Also adjust the enum name to lower case.
