    anolis: tpm: Add a driver for Loongson TPM device
    
    ANBZ: #21663
    
    Loongson security engine supports random number generation, hash,
    symmetric encryption and asymmetric encryption. Based on these
    encryption functions, TPM2 have been implemented in the Loongson
    security engine firmware. This driver is responsible for copying data
    into the memory visible to the firmware and receiving data from the
    firmware.
