[PATCH] soc: xilinx: vcu: modify the order of devices unregistration

[Ваторопин Андрей]

From: Andrey Vatoropin <a.vatoropin@xxxxxxx>

The order of registration of 'struct clk_hw' handles in
xvcu_clk_hw_register_leaf() does not correspond the order of
unregistration performed in xvcu_clk_hw_unregister_leaf().

Clean up the order and replace the duplicate !divider check with a more
appropriate one.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
