Input: elan_i2c - extend Flash-Write delay

KT Liao · dtor · commit 05f5c3857647 · 2017-09-22T10:07:38.000-07:00
The original 20ms delay is only marginally enough delay after a block write
operation during firmware update. Let's increase the delay to ensure that
the controller finishes up storing the page to avoid failures in the
firmware updates.
