soc/rockchip/rk3399: Ensure full eDP init sequence
This patch fixes 2 edp display issues: 1. When rk_edp_prepare fails >3 times, edp_init isn't run because while-condition is not satisfied. Then, only a partial init sequence is ran. This causes all aux transactions to fail. 2. If rk_edp_prepare never succeeds, coreboot never leaves link training stage due to infinite loop. Boot process is stuck. TEST=Boot past eDP initialization stage and make sure AP logs don't have show aux transaction fails.
