Rahul Tanwar d310124cd9 clk: intel: Avoid unnecessary memset by improving code
memset can be avoided in a loop if the variables used are declared
inside the loop. Move such variables declaration inside the loop
to avoid memset.

Rahul Tanwar 8529fc0aaa clk: intel: Use devm_clk_hw_register() instead of clk_hw_register()
To ensure that clks are unregistered in case of any failure, use
devm_clk_hw_register() instead of clk_hw_register().

Colin Ian King d036466330 clk: intel: remove redundant initialization of variable rate64
The variable rate64 is being initialized with a value that is never read
and it is being updated later with a new value.  The initialization is
redundant and can be removed.
