fingerprint: inscreen: allow to set_fod_rect at boot

We found that stock firmware calculates the fod rect
from resolution and a set of inscreen fingerprint
sensor position data at boot and then use set_fod_rect
command to tell the Kernel TSP driver.

Then the Kernel TSP driver wrote it to "sponge"
(presumably firmware of touchscreen panel).

It is not yet known what exactly was done with this
data but it is good to keep in line with stock
firmware when we can.
