mpp[150473]: mpp_rt: NOT found ion allocator mpp[150473]: mpp_rt: NOT found drm allocator 环境上没有 ion 或者 drm 来分配硬件内存，环境应该有点问题

Hi Herman,在用mpi_enc_test编码的时候，我也遇到相同的报错：mpp[1522]: mpp_rt: NOT found drm allocator。 有个问题请教一下：drm allocator 在mpp 硬件编码的时候，是不是必须的？否则无法分配内存？ 我在运行mpi_enc_test的时候不光看到mpp_rt: NOT found drm allocator，还看到mpp 内核驱动程序的告警：ioctls MPP_IOC_CFG_V1 failed ret -1 errno 12 Cannot allocate memory 似乎是无法分配内存。 感谢您百忙之中抽时间回答我得问题。

NOT found drm allocator 正常情况下平台都会有 drm 内存分配器，编译 mpp 的时候要带上 HAVE_DRM 标志
