osd: screen blank when Plugin HDMI after system bootup in 15s [1/1]

Browse Source 
PD#OTT-4292

Problem:
Root Cause:gralloc set afbcd = 1, but hwcomposer have no frame set,
hdmi plug and uboot logo update and osd_enable_hw() called, in this api,
there is a protection: if afbcd.enable set and phy_addr == 0 will
wait vsync till phy_addr != 0, this section code logic caused screen blank

Solution:
when gralloc set afbcd = 1, don't set afbcd.enable = 1,
it will update with hwcomposer post afbc frame.

Verify:
verify with Raven
