drm_hwcomposer: use latest patchset of "separate C compliant header file."

Revert "drm_hwcomposer: separate C compliant header file."

This reverts commit e7eff73fb428d53c5488ef470d9e401949eb1b00.

drm_hwcomposer: separate C compliant header file.

Creating C compliant header file drmhwcgralloc.h.
gralloc.tegra uses C compiler and depends only on code in drmhwcgralloc.h.
The module doesn't depend on anything present in new drm_hwcomposer.h.
This is required to fix the compile error.
