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.
