TCC88XX如何扩大CAMERA预留内存和buffer个数

1.修改lk中的文件include/arch/tcc_used_mem_tcc8800.h
  #define PMEM_CAM_SIZE 48
2.修改lk中的文件target/tcc8800_evm/atags.c
  target_atag_is_camera_enable():
  if(PMEM_CAM_SIZE == 48*SZ_1M)
3.修改kernel中文件drivers/media/video/tcccam/tcc_cam.h
  TCC_CAMERA_MAX_BUFNBRS 16
4修改hardware中文件hardware/telechips/common/libcamera/include/TCC_V4l2_Camera.h
