riscv: dts: spacemit: define all missing I2C controller nodes
SpacemiT K1 SoC is equipped with a total of nine I2C controllers,
ranging from I2C0 to I2C8.
Prior to this change, only I2C2 and I2C8 were explicitly defined
within the device tree. This patch comprehensively adds the
device tree node definitions for I2C controller 0, 1, 4 to 7.
The I2C3 node is not added because it belongs exclusively to the
secure domain which not used in the linux realm.
All newly added I2C nodes are set to "disabled" status by default,
allowing future board-specific device tree to enable and configure.
