e160f7d430 dm: core: Replace of_offset with accessor
At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

26f50fbed2 Revert "x86: broadwell: gpio: Remove the codes to set up pin control"
This makes the assumption that setting up pinctrl in cpu_init_r() is safe.
On samus we need GPIOs before relocation in order to support power control.
This commit fixes the following message on boot:

   initcall sequence ffe5c6f4 failed at call ffe01d3d (err=-1)
   ### ERROR ### Please RESET the board ###

In any case it seems better to leave init to driver model, so that it can
pick up the GPIO driver when it needs it. Since pinctrl is a dependency of
the GPIO driver, we may as well put the dependency there and avoid these
problems.

This reverts commit 9769e05bcf.

9769e05bcf x86: broadwell: gpio: Remove the codes to set up pin control
Now that we have set up pin control in cpu_init_r(), remove the
duplicated codes in the broadwell gpio driver.

8376aaddaf gpio: intel_broadwell: remove gpio_xlate routine
With the addition of GPIO_ACTIVE_LOW parsing in gpio-uclass,
the intel_broadwell driver doesn't need a custom xlate routine.
