The SD specification documents that the clock frequency should only be changed once gated (Section 3.2.3 - SD Clock Frequency Change Sequence). The current code first modifies the parent clock, gates it and then modifies the internal divider. This means that since the parent clock rate might be changed, the bus clock might be changed as well before it is gated, which breaks the specification. Move the gating before the parent rate modification.
