Add delay before reading GPIOs in gpio_base2_value()
This adds a 10us delay in between (re-)configuring and reading GPIOs in gpio_base2_value() to give the values stored some time to update. As far as I know this hasn't bitten us since the function was added, but adding a short delay here seems like the right thing to do.
