ae89d70758 drivers: clk: zynqmp: update divider round rate logic
[ Upstream commit 1fe15be1fb613534ecbac5f8c3f8744f757d237d ]

Currently zynqmp divider round rate is considering single parent and
calculating rate and parent rate accordingly. But if divider clock flag
is set to SET_RATE_PARENT then its not trying to traverse through all
parent rate and not selecting best parent rate from that. So use common
divider_round_rate() which is traversing through all clock parents and
its rate and calculating proper parent rate.

Add a NULL pointer check as clk_hw_get_parent can return NULL.

e39060e6e2 clk: zynqmp: make bestdiv unsigned
[ Upstream commit d3954b51b475c4848179cd90b24ac73684cdc76b ]

Divisor is always positive make it u32 *.
Also the arguments passed are currently of u32 pointers.
