[PATCH] w1: w1-gpio: Loosen timings to improve cold boot reliability

[Chris Morgan <macroalpha82@gmail.com>]

From: Chris Morgan <macromorgan@hotmail.com>

On my NTC CHIP whenever I do a cold boot any attached DIPs cannot be
found. Rebooting on the other hand appears to fix the issue. I found
that if I modified the timing slightly (but still within spec) the
w1 identification on cold boot became far more reliable.
