oneplus-bacon: fix swapped red and blue
This MR fixes problem described in issue #211 (closed) for oneplus-bacon,
a similar patch together with pixel format set to ARGB_8888
should fix
the same issue also on samsung-klte and fairphone-fp2.
I will open other two MR for the other phones to test and apply a similar patch.
Note that this MR undo the linux-oneplus-bacon patch applied with MR !258 (merged),
because that patch fixed the red screen problem in a wrong way, causing
the red and blue problem, see detailed explanation here.
This merge request fixes correctly both red screen problem and swapped red and blue problem.
