soc/intel/apollolake: make internal pulls weak for gpio inputs
The internal pulls for gpio_input_pullup() and gpio_input_pulldown()
were using fairly strong pulls. Weaken them so that external pulls
can override the internal ones. This matches the current assumptions
of lib/gpio.c.
BUG=chrome-os-partner:54949
BRANCH=None
TEST=Built and used on reef for memory config.
