riscv: dts: spacemit: k1: Add Banana Pi BPI-CM6 IO board

Browse Source 
The Banana Pi BPI-CM6 IO board combines the BPI-CM6 compute module with
an IO carrier board. The core module integrates the SpacemiT K1 SoC,
PMIC, DDR, eMMC, the eth0 PHY, and wireless connectivity. The companion
IO carrier board extends it by providing the eth1 PHY and exposing
standard interfaces, including dual Gigabit Ethernet, MicroSD, two USB-A
ports, a USB Type-C port, two PCIe M.2 slots, and a serial console.

The board also has two I2C EEPROMs. One is on the core module, which
stores factory manufacturing data and is marked read-only. The other is
on the carrier board, which is shipped unprogrammed and left writable
for evaluation purposes.

Add initial support for UART console, eMMC, SD card, I2C, EEPROMs,
PCIe, USB, and dual Ethernet interfaces.
