623c915ab8 drivers: pinmux: esp32: Fix using gpio as IO at the same time. 
Since PINMUX_INPUT_ENABLED == 1 and PINMUX_OUTPUT_ENABLED == 0,
we can not set a gpio port as input and output at the same time,

So we always set the gpio as input. Thus, the gpio can be used on
I2C drivers for example.

bed7698ac0 pinmux: esp32: Unnecessary iteration in "for" loop 
In this case: "pin == ARRAY_SIZE(pin_mux_off)" is invalid and it
isn't necessary to iterate.

d52de29fba esp32: Fix redefinition of BIT() macro 
Esp-idf defines the BIT macro that is also defined in Zephyr's
misc/util.h.  Fix the issue by including the esp-idf headers first, so
that a check in util.h won't redefine the macro if it's already
defined.
