83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

ebf48500df board: ti: am43: Fix DCDC3 voltage for epos-evm
A common voltage of 1.35V was being programmed for all am43 board
versions. EPOS-EVM Needs 1.20V for LPDDR2.

6183b29559 power: pmic: tps65218: Fix tps65218_voltage_update function
Currently while setting the vsel value for dcdc1 and dcdc2
the driver is wrongly masking the entire 8 bits in the process
clearing PFM (bit7) field as well. Hence describe an appropriate
mask for vsel field and modify only those bits in the vsel
mask.

8465d6a71a power: tps65218: define all valid VDD_MPU voltages
DCDC1 is used as VDD_MPU in all known boards,
let's define all other valid voltages for that
rail so it can be used by our boards.
