This series adds device tree support for the Tibbo LTPP3G2 board, which
is based on the Sunplus SP7021 SoC (quad-core ARM Cortex-A7).

Patch 1 adds peripheral device nodes to the SP7021 SoC DTSI for
peripherals whose drivers are already upstream: PWM, watchdog, eMMC,
and the L2SW Ethernet switch.

Patch 2 adds a DTS for the LTPP3G2 board itself, enabling those
peripherals and configuring the board-specific pinmux and Ethernet
topology. It also updates the defconfig to enable the relevant drivers.

Tested on the Tibbo LTPP3G2 board with linux-next 20260901.
