Refactor gpio_set_level() and gpio_pre_init()
gpio_set_level() now allows setting the pin level if GPIO_LOW or GPIO_HIGH is specified. Previously, stm32 platforms did this even though the definition of gpio_set_level() said it wouldn't work. Fixed gpio_set_level() not setting level after warm reboot on stm32 because it was checking the GPIO_DEFAULT flag in the wrong place. Fixed LM4 still mucking with alternate function settings and levels even if GPIO_DEFAULT was specified. And checked gpio_list[] and all of the calls to gpio_set_flags() to make sure everything still behaves the same way it did before (or better, in the case of actual bugs).
