mb/google/dedede: Update EC_MKBP_INT_L configuration
The concerned GPIO is configured as an open drain at the Embedded
Controller side without an external pull-up. This causes leakage in the
PP3300_A rail. So configure the GPIO to have a weak internal pull-up at
the SoC side.
BUG=b:151680590
TEST=Build the mainboard. Ensure that there are no leakages in the
PP3300_A rail.
