@FocusLuo please help to add platform information

root caused. vaCreateSurface will use gmmlib to manager allocation size for a P010 surface (416x240 to 896x256), but vaCreateImage does not use gmmlib, so the size is mismatch when call vaGetSurface. will fix it ASAP

This issues still can be reproduced with media_driver 36b3a0a .
HEVC_10bit_allegro10 : passed 173 failed 42 on CFL , passed 175 failed 40 on KBL .
hevc_10bit_jvt : only TSUNEQBD_A_MAIN10_Technicolor_2.bin failed.

@zhuqingliang , I will close the issue, some cases pass, some cases failed, we need a new issue which can be reproduced easily to handle it
