[U-Boot] [RFC 1/1] configs: rk3288: SPL file must fit into 32 KiB

[Heinrich Schuchardt]

The SPL image for the rk3288 boards has to fit into 32 KiB. This includes
4 KiB for the device tree and up to 2 KiB for the file header.

Without the patch we missed to see that the TinkerBoard
spl/u-boot-spl-dtb.bin file is too big.
