clk: qcom: branch: Extend invert logic for branch2 mem clocks

Browse Source 
Some clock branches require inverted logic for memory gating, where
disabling the memory involves setting a bit and enabling it involves
clearing the same bit. This behavior differs from the standard approach
memory branch clocks ops where enabling typically sets the bit.

The mem_enable_invert to allow conditional handling of these sequences
of the inverted control logic for memory operations required on those
memory clock branches.
