rk3288: Enable HDMI hang boot and no Linux log

[Jagan Teki]

Hi,

Is linux-next support HDMI on rk3288? I'm trying to enable hdmi (with
ddc-i2c-bus) statically along with Linux boot logo. Observed an kernel
boot hang, didn't find whats wrong because DWC MHL PHY as detected
from the log.

Here is the full log[1] please let me know if I miss any?
