clk: at91: clk-master: check if div or pres is zero
Check if div or pres is zero before using it as argument for ffs().
In case div is zero ffs() will return 0 and thus substracting from
zero will lead to invalid values to be setup in registers.
Fixes: 7a110b9107ed8 ("clk: at91: clk-master: re-factor master clock")
Fixes: 75c88143f3b87 ("clk: at91: clk-master: add master clock support for SAMA7G5")
