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.

The command can only be used from full U-Boot, so do not build it into
SPL.

Removed several EEPROM bit dependencies:
- for dt aliases that don't exist and thus don't ever do anything
(pcie,lvds1,uart*,vpu,csi*,hdmi_in,hdmi_out,cvbs_in,cvbs_out,gps)
- for features that don't effect bus ordering or have no detrimental affect
if erroneously enabled when not present (ahci,nand,i2c*)
- for features that have little to no impact on being erroneously enabled
but high impact if erroneously disabled (can*, spi*)
- for features that have an high adverse affect of not being set when they
should and no adverse affect of being set when they
shouldn't (ipu*).
Removing these means the following:
- these no longer are supported with the econfig command
- these no longer affect the device-tree in any way

The Gateworks Ventana EEPROM contains a set of configuration bits that
affect the removal of device-tree nodes that support peripherals that do not
exist on sub-loaded boards. This patch adds:
- a structure to define a config bit name, dt node alias, bit position
- an array of supported configuration items
- an econfig command to get/set/list configuration bits
- use of the array when adjusting the FDT prior to boot

Split the read_eeprom function out so that it can be shared (ie with SPL)
