rockchip: rk3308: Generate ethaddr based on cpu id
Like other Rockchip SoCs the RK3308 has cpu id programmed into OTP
memory. The rockchip_otp driver already support the RK3308 variant.
However, the device tree is missing a node to enable use of OTP.
Add the missing otp node to soc u-boot.dtsi, enable the rockchip_otp
driver and enable use of misc_init_r() to set ethaddr based on cpu id.
