Chipone: Fix compatibility with 5.4.0 api

Browse source 
This commit is a port from https://gerrit.mot.com/#/c/1795715/
       to focaltech_0flash_v2_mmi

At GKI 1.0 the VTS tests should use GKI and GKI does not allow the use of
        input_get_new_minor, so VTS tests does not have working touchscreen
        Fix it definitely using the correct alloc api
