i.MX6DL/S: add drive-strength back to pads DISP0_DAT2/DAT10

The pad settings for DISP0_DATA02 and DISP0_DAT10 were not
set in the same way as DISP0_DAT00-23, causing much flicker
in parallel RGB displays on Dual-Lite and Solo processors.

These settings now match the i.MX6 Dual and Quad core versions.

Note that this fixes a regression in commit b47abc36 and that
this is the second time we've had a regression on these two
pads (See commit e654ddf7).
