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.
