[stm32f4-ltdc] The Makefile change got lost somehow
[stm32f4-ltdc] commented out assertions. will remove them later
[stm32f4-stdc] fixed includes
[stm32f4-usb] removed the ep init send flags
              they are probably needed for other usb-implementations?
[stm32f4-usb] the stack should work now also for otg_fs
if the two commented out flags on line 113 in usb_fx07_common.c have no
influence in the functionality of otg_fs
I also changed my fixed fifo fix (max_packet+4-1)>>2
