ENGR00116086 fb: mmap fail for first time for fb2
If did not set_var, fb driver will not allocate buffers. If user call
fb_set_var with the same size as fb default setting(in mxcfb_probe,
usually 240x320),fb drvier will not call mxcfb_set_par if no
FB_ACTIVATE_FORCE flag set, which will make mmap fail.
Allocate fb buffers in mxcfb_probe avoid such issue, but it will consume
memory at the very beginning.
