MGS-955 GPU:Integrate GPU module

1. Upstream 5.0.11p7 driver to kernel

2. Add the GPU configuration to imx6q.dtsi

3. Remove IRQF_DISABLED in GPU driver
The IRQF_DISABLED has been removed from 4.1.0 kernel. To accomodate with
the change, add version check logic and use 0x0 instead of IRQF_DISABLED
from 4.1.0 kernel on.

4. Convert file->f_dentry->d_inode to file_inode() in GPU driver
The file struct has changed since 3.19. Changed the usage in GPU driver
too.

5. Add version check for CONFIG_PM_RUNTIME
The CONFIG_PM_RUNTIME will never be used in 4.1.0 kernel. Add version
check to avoid calling it in GPU driver.
