gpu: MALI_DMA_BUF_MAP_ON_DEMAND by default [1/1]

PD#SWPL-18288

Problem:
kernel still use the legacy mode

Solution:
11.2 new DMA-BUF mapping from the Mali release note.
From r18p0-01rel0 version of the DDK the DMA-BUF memory
will be mapped for the GPU when it is imported into the DDK.
This will reduce the CPU load by avoiding unnecessary work
to build GPU page tables potentially every time the work using DMA-BUF memory
is submitted to GPU.

Verify:
