USB: dwc3: msm: Add support for vote/devote aggre2_snoc_axi_clk
It is required to put/get vote for aggre2_snoc_axi_clk before turning
ON USB core clock for read/write transactions to be successful over
NOC from USB->DDR. Hence add support for voting aggre2_snoc_axi_clk
before enabling USB core clock as part of exiting low power mode.
