clk: msm: clock: Add depends field for mmagic_ahb_clk dependent clocks 



Add the depends field for clocks which need the mmss_mmagic_ahb_clk
to be turned on/off before they are enabled/disabled. Adding this
field takes care of this dependency from the clock driver code.
The bus driver no longer needs to place an explicit vote on the
mmss_mmagic_ahb_clk and only needs to scale it depending on the
bandwidth request from the client.
