Now that Linux has accepted these tags, move the device tree files in
U-Boot over to use them.

9f0deae6d5 arm: pdu001: Fix dt to work with the current am33xx dtsi files
The changes introduced with commit 6337d53fdf ("arm: dts: sync am33xx
with Linux 5.9-rc7") prevent the PDU001 from operating correctly.
This patch fixes the configuration of the pin multiplexer and uart3.

ff94c15a3c video: omap: add panel driver
The previous version of am335x-fb.c contained the functionalities of two
drivers that this patch has split. It was a video type driver that used
the same registration compatible string that now registers a panel type
driver. The proof of this is that two compatible strings were referred
to within the same driver.
There are now two drivers, each with its own compatible string,
functions and API.
Furthermore, the panel driver, in addition to decoding the display
timings, is now also able to manage the backlight.

72e0a0e1c7 arm: dts: am335x: add 'u-boot, dm-pre-reloc' to panel
Add the "u-boot,dm-pre-reloc" property to the "ti,tilcdc,panel"
compatible node. In this way the video-uclass module can allocate the
amount of memory needed to be assigned to the frame buffer.
For boards that support Linux the property is added to the *-u-boot.dtsi
file since it is a u-boot specific dt flag.

Ran building tests with CONFIG_AM335X_LCD enabled and disabled for the
following configurations:
 - brxre1_defconfig           --> success
 - am335x_guardian_defconfig  --> success
 - am335x_evm_defconfig       --> success
 - da850evm_defconfig         --> failure with CONFIG_AM335X_LCD enabled

Enabling CONFIG_AM335X_LCD in da850evm_defconfig causes building errors
even without applying the patch. The driver has never been enabled on the
da850 and must be adapted for this platform.

2aadff0feb arm: am335x-pdu001: Enable CONFIG_BLK and CONFIG_DM_MMC
This patch enables CONFIG_BLK as well as CONFIG_DM_MMC for the PDU001
board. It depends on Patrice Chotard's patch 'power: regulator: denied
disable on always-on regulator' which prevents power cycling the vmmc
supply. Without this patch the board will not boot as vmmc is
unfortunately used by other board components, not just eMMC and micro SD
card. Furthermore my patch 'dts: am335x-pdu001: Fix polarity of card
detection input' is required to boot from external micro SD card. Without
this patch no SD card will be detected and hence booting will fail.

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.
