It turns out tinker-rk3288 SPL no longer fits in 2019.04 and previously
worked fine in 2019.01.

Warning: SPL image is too large (size 0x8800) and will not boot
Error: image verification failed

built with gcc-linaro 6.3.2017.02

bisecting led to the pinctrl changes.

with SPL_PINCTRL_ROCKCHIP disabled it fits and U-Boot output on
serial gets as far as the efi loader then no output appears on serial
when a kernel is loaded.
