I suspect making a wrapper around struct clk_branch would be a better
approach so that we don't bloat all the other clk_branch structures that
exist in the qcom clk drivers.

How many of these are going to be using these new registers? It may also
make sense to do that for hardware clock gating as well, but I'm not
really sure. Anyway, the idea is
struct clk_mem_branch {
u32 enable_reg;
u32 ack_reg;
u8 ack_bit;
struct clk_branch branch;
};
and then a container_of define. Plus, you can put some comment above the
structure to describe when these clks are used.
