ceb9190969 dm: replace dm_dbg() with pr_debug()
As we discussed before in ML, dm_dbg() causes undefined reference
error if #define DEBUG is added to users, but not drivers/core/util.c

We do not need this macro because we can use pr_debug() instead, and
it is pretty easy to enable it for the DM core by using ccflags-y.

766c28a548 dm: include <dm/util.h> from drivers/core/util.c
Fix sparse warnings "... was not declared. Should it be static?"

Also, fix redefinition of dm_warn/dm_dbg.

d905cf7365 dm: Return actual bools in dm_fdt_pre_reloc
Documentation says that we're returning true/false, not 1/0 so adapt
the function to return actual booleans.

27326c7ee2 dm: allow limiting pre-reloc markings to spl or tpl
Right now the u-boot,dm-pre-reloc flag will make each marked node
always appear in both spl and tpl. But systems needing an additional
tpl might have special constraints for each, like the spl needing to
be very tiny.

So introduce two additional flags to mark nodes for only spl or tpl
environments and introduce a function dm_fdt_pre_reloc to automate
the necessary checks in code instances checking for pre-relocation
flags.

The behaviour of the original flag stays untouched and still marks
a node for both spl and tpl.

6494d708bf dm: Add base driver model support
Add driver model functionality for generic board.

This includes data structures and base code for registering devices and
uclasses (groups of devices with the same purpose, e.g. all I2C ports will
be in the same uclass).

The feature is enabled with CONFIG_DM.
