With DM_GPIO, gpio parameters like ACTIVE_(LOW/HIGH) are to be
parsed in xlate gpio drivers-ops. Since xlate is not implemented
in omap_gpio driver, the driver considers all gpio to be
ACTIVE_HIGH which is the default case and fails to return actual
gpio status for ACTIVE_LOW gpios. So adding .xlate ops to
omap_gpio.

Stop prefixing the axp functions for setting voltages, etc. with the
model number, there ever is only one pmic driver built into u-boot,
this allows simplifying the callers.

After rework in lib/fdtdec.c, the function fdtdec_get_addr()
doesn't work for nodes with #size-cells property set to 0.

To get GPIO's 'reg' property, the code should use one of:
fdtdec_get_addr_size_auto_no/parent() function.

Fortunately dm core provides a function to get the property.

This commit reworks function gpio_exynos_bind(), to properly
use dev_get_addr() for GPIO device.

This prevents setting a wrong base register for Exynos GPIOs.

Tested on: Odroid U3/X2, Trats, Trats2, Odroid XU3, Snow (by Simon).

In order to make it clear what the parameters to set_config() and
set_direction() mean, and similarly for the return values from the
respective get_*(), define named constants for these values.

Disassembly shows no diff in the generated code, except that the
order of the code in the branches of tegra_gpio_get_function() gets
modified without affecting behaviour.
