The _has_i2c_master() should return 1 if there is an I2C master.
The logic was incorrectly inverted. So fix it now.

This adds a simple driver for MMIO-based GPIO ports.
It does not trigger any interrupts due to pin level at this moment.

This adds the driver for I2C-based PCAL9535A GPIO chip.
This currently only enables minimal set of features of the chip for
very simple input/output operations, and does not support interrupt
yet.

This change puts the DW GPIO Kconfig selections inside GPIO menu.
This also groups all DW GPIO related selections under GPIO_DW.

The code fragment to bind the instances of the GPIO driver were being
replicated in every platform_config.c This code is not platform
specific but is driver specific.
All the information required to bind a driver instance comes from
CONFIG_ variables. Having the binding code with the driver code
avoids duplicating the code fragments in each platform where the
driver may be used.

When configured as GPIO_ACCESS_BY_PIN, the callback should
be called only if the pin is enabled and received an interrupt.

This commit fixes the set bit function.
If the value to set is different from zero, then
the indicated bit will be set.

[DL: captilize commit message title; fixed some whitespaces;
changed the __initconfig_gpio_* from level 0 to level 1,
which is the level of pure_init; and added include path
to board.h; ]
