Revert "ARM: tegra: dc: program active mux for cursor"
This reverts commit 3bb0d7f08cde9ef74c7419218187a3ca53b961c1.
Cursor programming to ACTIVE copy directly is bad and not
desired programming sequence, which has caused unexpected
cursor window rendering across whole screen suddenly.
With this change, it programs to ASSEMBLY copy and latch
them into ACTIVE copy after GENERAL_ACT_REQ.
