gdc: add gdc cpu cost optimize [1/1]
PD#SWPL-7422
Problem:
gdc ioctl have cpu usage issue
Solution:
1. dma buffer alloc gdc module,when dma buf exported, fd and phys
address can be recorded.driver can get phys address via fd internally.
2. dmabuf alloc by other driver module, need used gdc_dma_buffer_map/
gdc_dma_buffer_unmap to get phys address.
Verify:
Newman & W400 board
