dd504db5cd ARM: dts: ti/omap: omap3-gta04: use proper touchscreen properties
Specify the dimensions of the touchscreen propertly so that
no userspace configuration is needed for it.
Tested with x11 and weston on Debian bookworm.

What is in now is some debris from earlier tries to handle
scaling in kernel:

0cfbd7805f ARM: dts: ti/omap: gta04: fix pm issues caused by spi module
Despite CM_IDLEST1_CORE and CM_FCLKEN1_CORE behaving normal,
disabling SPI leads to messages like when suspending:
Powerdomain (core_pwrdm) didn't enter target state 0
and according to /sys/kernel/debug/pm_debug/count off state is not
entered. That was not connected to SPI during the discussion
of disabling SPI. See:
https://lore.kernel.org/linux-omap/20230122100852.32ae082c@aktux/

The reason is that SPI is per default in slave mode. Linux driver
will turn it to master per default. It slave mode, the powerdomain seems to
be kept active if active chip select input is sensed.

Fix that by explicitly disabling the SPI3 pins which used to be muxed by
the bootloader since they are available on an optionally fitted header
which would require dtb overlays anyways.

Drop omap36xx compatible as done in other omap3630 devices.
This has apparently fallen through the lattice.

724ba67515 ARM: dts: Move .dts files to vendor sub-directories
The arm dts directory has grown to 1559 boards which makes it a bit
unwieldy to maintain and use. Past attempts stalled out due to plans to
move .dts files out of the kernel tree. Doing that is no longer planned
(any time soon at least), so let's go ahead and group .dts files by
vendors. This move aligns arm with arm64 .dts file structure.

There's no change to dtbs_install as the flat structure is maintained on
install.

The naming of vendor directories is roughly in this order of preference:
- Matching original and current SoC vendor prefix/name (e.g. ti, qcom)
- Current vendor prefix/name if still actively sold (SoCs which have
  been aquired) (e.g. nxp/imx)
- Existing platform name for older platforms not sold/maintained by any
  company (e.g. gemini, nspire)

The whole move was scripted with the exception of MAINTAINERS and a few
makefile fixups.
