Erick Archer 252c31a90e clk: hisilicon: Use devm_kcalloc() instead of devm_kzalloc()

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.

So, use the purpose specific devm_kcalloc() function instead of the
argument size * count in the devm_kzalloc() function.
