touchpad_elan: Reload watchdog when programming
When using larger block sizes (e.g. 4096 bytes), the write operations
take too long, which often causes a watchdog reset.
Fix this by reloading the watchdog after programming
every 64 bytes page.
BRANCH=poppy
BUG=b:80167548
TEST=Copy old touchpad FW to soraka, build staff, make sure FW
can be updated.
