Subject: [PATCH V1 2/2] pinctrl: qcom: spmi-gpio: Set is_enabled flag in set_mux()

From: Fenglin Wu <fenglinw@...eaurora.org>

The initial value of is_enabled flag is read out from hardware in
pmic_gpio_populate(), and it will be set in pmic_gpio_config_set() if
pinconf is defined. For any GPIOs disabled initially in hardware which
only have pinmux defined, they won't be enabled in pmic_gpio_set_mux()
calling. So set is_enabled flag in set_mux() to ensure the GPIO module
could be enabled in above case.
