pinctrl: qcom: spmi-gpio: Update GPIO EN_CTL when setting pin config 



GPIO is expected to be disabled iff PIN_CONFIG_BIAS_HIGH_IMPEDANCE is
configured. Update is_enabled flag in config_set() so that it can
reflect GPIO status correctly. Also modify EN_CTL register based on
is_enabled flag in config_set() to configure the GPIO properly.
