clk: asm9620: Remove 'hw' local variable that isn't checked

The 'hw' pointer local variable in this function became unused after
commit f5290d8e ("clk: asm9260: use parent index to link the
reference clock"). Remove it to silence an unused but set variable
warning.

 drivers/clk/clk-asm9260.c:258:17: warning: variable 'hw' set but not used [-Wunused-but-set-variable]
           struct clk_hw *hw, *pll_hw;
                          ^
   1 warning generated.
