Subject: [PATCH][next] net: microchip: sparx5: remove redundant store to variable clk_hz

The store to clk_hz is redundant since clk_hz goes out of scope on the
return. Fix this by replacing the *= operator with just * to remove
the store back to clk_hz.

Cleans up clang scan build warning:
warning: Although the value stored to 'clk_hz' is used in the enclosing
expression, the value is never actually read from 'clk_hz'
