drm/msm: Do not declare msm_framebuffer_init() as static

Declare msm_framebuffer_init() in msm_drv.h and remove the static
qualifier. The function will be required in msm_fbdev.c after inlining
msm_alloc_stolen_fb().

Also move msm_framebuffer_init() before msm_framebuffer_create(), so
that it can later be made static again. Prepares msm's fbdev emulation
for using client buffers.
