clk: qcom: clk-aop-qmp: Update CLK_ENABLE_HAND_OFF flag to 0

Remove CLK_ENABLE_HAND_OFF flag. Supporting this flag
will bring in clock framework change to handle or update hand off
flag during clk core init and clk tree unused calls.
Earlier CLK_ENABLE_HAND_OFF was added to gain performance
optimization by avoiding multiple AOP requests to enable qmp clocks.
If necessary, similar optimization can be supported with an
explicit proxy vote that is not removed until sync-state.
Currently QDSS driver can vote on the qmp clks as necessary.
