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.
