Use predefined bit masks in operations where only the magic half or
only the count half of the 32-bit value are processed.

Add new Kconfig option, SYS_BOOTCOUNT_MAGIC, to select the boot
counter magic word. This can be useful ie. in case the entire
boot counter register is not usable.

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.

Some am33xx boards may not use the RTC block for bootcount (as it may
not be wired up for the board) and use some other facility. So add
another symbol for the bootcount driver for the IP block.

The RTC IP block here provides 3 scratch registers. Currently when
using DeepSleep on am335x the scratch0/1 registers are used so moving
ourself to scratch2 makes cooperation easier.

Create a common header file for the RTC IP block that is shared between
davinci and am33xx.

This patch moves all bootcount implementations into a common
directory: drivers/bootcount. The generic bootcount driver
is now usable not only by powerpc platforms, but others as well.
