msm: mdss: increase mdp hw recovery timeout

Browse source 
In some cases, display driver times out waiting
for the mdp hw recovery to complete, causing the
device to panic; however in some cases hw is
able to successfuly complete the recovery after
some more time.
This change increases the timeout, so driver
waits more time for the hw to complete the
recovery sequence.
