jtag/drivers/am335xgpio: do not configure push-pull inputs as output

Previously, if a pin was configured as ADAPTER_GPIO_INIT_STATE_INPUT and
its drive value was ADAPTER_GPIO_DRIVE_MODE_PUSH_PULL, initialize_gpio
would configure the pin as an output.

The set_gpio_value function is optimized to not set the direction for
pins configured as ADAPTER_GPIO_DRIVE_MODE_PUSH_PULL as it only needs to
be set once. When initialize_gpio performs this setup, it checked only
that the drive value was ADAPTER_GPIO_DRIVE_MODE_PUSH_PULL to set the
output direction but did not exclude input pins which have already had
their direction set.

Now, input pins are ignored when initialize_gpio checks for
ADAPTER_GPIO_DRIVE_MODE_PUSH_PULL to set the mode to output.
