In zonda_pll_adjust_l_val() replace the divide operator with comparison
operator to fix below build error and smatch warning.

drivers/clk/qcom/clk-alpha-pll.o: In function `clk_zonda_pll_set_rate':
clk-alpha-pll.c:(.text+0x45dc): undefined reference to `__aeabi_uldivmod'

smatch warnings:
drivers/clk/qcom/clk-alpha-pll.c:2129 zonda_pll_adjust_l_val() warn: replace
divide condition '(remainder * 2) / prate' with '(remainder * 2) >= prate'
