We intended to clear the bits of CLK_SRC_TOP2 register, instead we were
writing on the reserved bits of src_core1 register. Since the default
value of clk_src_top2 register were itself zero, this typo was not
creating any big issue. But it is better to fix this error for better
readability of the code.
