CHROMIUM: drm/udl: Fixed problem with UDL adpater reconnection

Fixed problem with DisplayLink and DisplayLink certified adapers in
kernel v3.18 when adapter doesn't want to work if it was initialized
with disconnected DVI cable. Now udl driver checks and updates its
connection state every 10 seconds. Now UDL driver retreives all edid
data blocks instead of only base one. Previous approch could lead to
improper initialization of video mode with certain monitors.

BUG= chromium:712947 , chromium:737842 , chromium:765354 
TEST=Boot Samus with connected DL165 adapter, but with disconnected
DVI cable. Connect DVI cable after system will start. DL165 adapter
should work.
