soc: imx: gpc: Disable 6sl display power gating for ERR006287
The imx6sl chip errata document describes ERR006287 like this:
> Upon resuming from power gating, the modules in the display power domain
(eLCDIF, EPDC, PXP and SPDC) might fail to perform register reads
correctly.
> When the modules listed above are used, do not use power gating on the
display power domain.

Handle this in the safest possible way by keeping the DISP domain
always-on.
