Add reset control support in USB glue logic. This needs to control
the external clocks and resets for the logic before accessing the
glue logic.
The USB dm tree when using dwc3-generic is the following:
USB glue
+-- controller (need controller-reset)
+-- controller-reset (need syscon-reset)
+-- phy
The controller needs to deassert "controller-reset" in USB glue before
the controller registers are accessed. The glue needs to deassert
"syscon-reset" before the glue registers are accessed.
The glue itself doesn't have "syscon-reset", so the controller-reset
controls "syscon-reset" instead.

In case the ops is not implemented, return 0 in the core right away.
This is better than having multiple copies of functions which just
return 0 in each reset driver. Drop all those empty functions.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

When you enable CONFIG_OF_LIVE, you will end up with a lot of
conversions.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

This function name conflicts with our desire to #define free() to
something else on sandbox. Since it deals with resources, rename it to
rfree().

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

- Merge sys_reset data of LD4, Pro4, sLD8 and Pro5
- Merge sys_reset data of LD11 and LD20
- Use primitive UNIPHIER_RESETX() macro because bit assignments for
system reset will be changed for every SoC in the future
- Add NAND and eMMC resets

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.
