In some situation, QSPI controller is already configured by an early
boot stage, adding reset support will insure that QSPI controller is
started from a pristine state.

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.

Use available DM stm32_timer driver instead of dedicated
mach-stm32/stm32fx/timer.c.
Remove all defines or files previously used for timer usage in
arch/arm/include/asm/arch-stm32fx and in arch/arm/mach-stm32/stm32fx
Enable DM STM32_TIMER for STM32F4/F7 and H7.

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.
