arm64: dts: ti: k3-am623-pfc-750-8400: add Rev.3 support via DT overlay-boot

Browse Source 
The PFC400-750-8400 exists in two hardware revisions, each consisting
of several sub-PCBs identified by a Leiterplattenkennung (LPK). Rev.2
(LPK p0003xxx) was supported by a monolithic DTS. Rev.3 (LPK p0004xxx)
introduces new sub-PCB variants that cannot be described alongside
Rev.2 in a single static DTS.

Overlay-boot is introduced to support both revisions simultaneously.
U-Boot reads the LPK from each sub-PCB's ID EEPROM at boot and applies
the matching set of DTBOs to the shared base DTB.

Base DTS restructured:
- Strip k3-am623-pfc-750-8400.dts to the minimal shared base; remove
  direct includes of wosm, baseboard, kbus and interaction dtsis.
- Extract TPS65219 PMIC, 4 GiB memory map, voltage regulators and SD
  card voltage-selector GPIO into new k3-am623-pfc-750-84xx-wosm-base.dtsi,
  shared across both revisions.
- Correct buck1 VDD_CORE min-microvolt from 750 mV to 850 mV, per TI
  recommendation for stable CPU frequency scaling. The PMIC NVM was
  updated accordingly on Rev.3 hardware.
- Enable DTC symbol export (-@) for the 750-8400 DTB so overlays can
  resolve labeled references at runtime.
- Export a stable leds_m4 symbol on the M4 LED wrapper node and mark
  it status = disabled; defer LED child nodes and activation entirely
  to the interaction overlay, establishing a clean overlay interface.
- Add fitImage.its packaging the base DTB and all nine DTBOs into a
  U-Boot FIT image for overlay-boot.

DTS overlay compatibility fixes applied to shared dtsis:
- Replace bare `/ {` with `&{/}` in kbus, interaction and wosm dtsis.
- Add explicit #address-cells/#size-cells to &main_i2c1, &mcu_spi0,
  &main_spi0 and &ospi0 fragments to prevent DTC standalone warnings.
- Move rts-gpios from k3-am623-pfc-rs485.dtsi to the board-level
  k3-am623-pfc-750-8xxx-common.dtsi.
- Strip shared interaction dtsi to truly common i2c1 peripherals only
  (HW-ID EEPROM, ST25DV NFC tag); PCA9552 drivers, their reset-pin
  pinctrl and all leds-group-multicolor RGB groups were incorrectly
  shared and are moved exclusively into the p0003965 overlay.

Nine hardware-variant overlays across four subsystems:

WOSM:
- p0004037 (Rev.2): baseline WOSM, no additions.
- p0004263 (Rev.3): adds MRAM reset GPIO, dual EM-module reset GPIOs,
  second RS485 (UART3) pinctrl and CAN (MCAN0) pinctrl.

Base board:
- p0003964 (Rev.2): restores microchip,single-led-mode on KSZ9477.
- p0004305 (Rev.3): corrects KSZ9477 Ethernet port labels to reflect
  changed port-to-PHY routing on Rev.3 PCB (ethX1<->ethX3,
  ethEM<->ethX4). baseboard.dtsi retains Rev.2 labels as default.
- p0004224: overrides UART4 RS485 pinctrl and GPIO RTS for boards
  with a relocated RS485 transceiver.

Local bus:
- p0003978 (Rev.2): baseline K-Bus / OMS configuration.
- p0004067 (Rev.3): routes RUN/STOP switches through dedicated MCU
  GPIOs; disables the legacy combined oms_stop_run node.

Interaction board:
- p0003965 (Rev.2): owns the full PCA9552 LED subsystem — reset-pin
  pinctrl, led_bar60/61 drivers and ten leds-group-multicolor RGB
  groups.
- p0004065 (Rev.3): activates the M4 firmware LED wrapper (&leds_m4)
  and defines all eight LED child nodes.
