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()

Get initial value of is_enabled flag by reading REG_EN_CTL register
so that it can reflect the correct hardware enable state before
setting pin config.

Currently, is_enabled flag is always set to true in pmic_gpio_populate()
regardless of the hardware real time status. This is not correct and it
gives the wrong information for the GPIOs which are disabled initially
in hardware. Add two patches to fix this: One is set the is_enab
From: Fenglin Wu
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.
