XZ3 Touchsreen unreliable at home partition unlock screen

[haelge]

The encryption screen does not respond to touch events. (Might be related to #183)

To be able to unlock the home partition I have to reboot 4-5 times, I couldn't figure out an "always work schme". It seems to be shear luck since it doesnt matter if I simply reboot via long power-off press, long power-off with volume up pressed until phone vibrates once and long power-off with volume pressed until phone vibrates three times. All these actions can rarely result in a boot with working touchscreen.

Observed on 4.5.0.21 and 4.5.0.24.

I'd happy to post any logs that might be of interest, but havn't found anything suspicious myself, but this may be due to poor knowledge on my part

I have seen this once in a while on XZ2 and XZ2c. I have no idea how to fix it and what is causing it. Fortunately, boot is relatively rare activity and we can use the phone fine after that part is passed

@haelge, even if just for the record, if you can upload logs when this happens it would be helpful.
