Revert "atmel_lcdfb: Adjust HFP calculation so it matches the manual."
This reverts commit 5d910426a6e80194a50e33351c91abcad266c809. Nicolas Ferre <nicolas.ferre@atmel.com> wrote: "Unfortunately this is not true for all the SoC that embed the atmel_lcdfb... So I may need to rework this patch but it is certainly not applicable in the current form." Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
