SiLabs: port_api: Allow individual values on output pins and fix init 

Previously, all pins in an mbed Port were set to the same value.
Use GPIO_PortOutSetVal to directly write the desired value to
the pins.

During port initialization the pin mode for input pins was set incorrectly.
Now, input pins are directly set to Input (gpioModeInput) and output pins to
PushPull (gpioModePushPull).
