In rk3126, when aclk_vio0\aclk_vio1\hclk_vio were reparented from the
default parent gpll_div2 to gpll in clk_init, the temporary rates
are too high and may lead to failture in VIO idle_request later.
To slove this problem, VIO clocks are modified to auto select parent
and consider the order of reparent and set_div when set_rate.

between hcd_reinit() and cil_interrupt handler.
hcd_reinit() should get core_if->lock before modify this
lock, so that can prevent competition between cil_interrupt
handler and hcd_reinit(), hcd_reinit() be scheduled while
cil_interrupt handler holding core_if->lock, hcd_reinit() modify
the lock then previous core_if->lock will never be unlocked.
