7d05e33de8 [mpp]: add /dev/mpp_service support
Add a new ioctl mode for kernel-4.19 or later.
Tips:
    1. There will be only one device /dev/mpp_service in kernel.
       User should use client type to distinguish different device.
    2. Each codec use the same function as before.
    3. Ioctl magic changes from VPU_IOC to MPP_IOC.
    4. Update structure for ioctl argument.
	Original structure:
	    data_ptr | size
	In this mode has many sortcommings:
	a) Need many ioctl cmd for different requirements.
	b) Data_ptr not to differ library for 32 or 64 system.
	c) Contain only one info ioctl once.

    New data structure:
        cmd_type | flags | size | offset | data_ptr
    a) Cmd_type works like previous ioctl cmd.
    b) Flags is extend to mark current data for any purpose.
    c) Size is the same as before.
    d) Data_ptr use 32 bits build in 32 system while 64 bits in 64 system.
