da409ccc4a dm: core: Replace of_offset with accessor (part 2)
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.

a821c4af79 dm: Rename dev_addr..() functions
These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

9d922450aa dm: Use dm.h header when driver mode is used
This header includes things that are needed to make driver build. Adjust
existing users to include that always, even if other dm/ includes are
present

46f51dc9c7 Add 16-bit single register pin controller support
Enables the pinctrl-single driver to support 16-bit registers. Only
32-bit registers were supported previously. Reduced width registers are
required for some platforms, such as OMAP.
