[PATCH 3/3] riscv: dts: spacemit: Add K3 eFuse and temperature trim cells

[Jiayu Du]

Add the K3 eFuse controller with its AES_WTM clock and reset. Describe
fixed-layout cells for the temperature calibration parameters stored in
bank 0 and bank 7, using controller-relative offsets.

Leave the controller disabled for board-level enablement.
