This adds a driver to access the efuse on Amlogic Meson6, Meson8 and Meson8b SoCs. These SoCs are accessing the efuse IP block directly through the registers in the "secbus" region. This makes it different from the Meson GX efuse driver which uses the "secure monitor" firmware to access the efuse. The efuse on Meson6 can only read one byte at a time, while the efuse on Meson8 and Meson8b always reads 4 bytes at a time. The new driver supports both, but due to lack of hardware Meson6 support was not tested. The hardware also supports writing. However, this is currently not supported by the driver.
