drm/rockchip: vop: fix iommu page fault when resume ...
Iommu would get page fault with following path:
vop_disable:
1, disable all windows and set vop config done
2, vop enter to standy, all windows not works, but their registers
are not clean, when you read window's enable bit, may found the
window is enable.
vop_enable:
1, memcpy(vop->regsbak, vop->regs, len)
save current vop registers to vop->regsbak, then you can found
window is enable on regsbak.
2, VOP_WIN_SET(vop, win, gate, 1);
force enable window gate, but gate and enable are on same
hardware register, then window enable bit rewrite to vop hardware.
3, vop power on, and vop might try to scan destroyed buffer,
then iommu get page fault.
Move windows disable after vop regsbak restore, then vop regsbak mechanism
would keep tracing the modify, everything would be safe.
