[U-Boot] [U-Boot, 1/2] rockchip: dts: rk3399-puma: put environment (in MMC/SD configurations) before SPL

[Philipp Tomsich]

> As our SPL stage can grow quite large (80KB+ are not unusual) on the
> RK3399-Q7, the default setting for the environment location (in
> include/configs/rockchip-common.h) can overlap our SPL.
> 
> This change finally makes use of the 'u-boot,mmc-env-offset' DTS
> property to override the environment location and put it at 16KB into
> the device, which is right before the SPL (located at 32KB).
