arm64: defconfig: Enable Rockchip OTP memory driver

The Rockchip one-time programmable memory driver provides access to
various SoC specific information, e.g. leakage currents of the
CPU/GPU/NPU components found on a RK3588 SoC.

Enable the driver as built-in to allow client device drivers (e.g.
cpufreq) to access the required data for proper settings adjustment.
