pwm: meson: Add check for error from clk_round_rate()
clk_round_rate() can return not only zero if requested frequency can not
be provided but also negative error code so add check for it too.
Also change type of variable holding clk_round_rate() result from
unsigned long to long. It's safe due to clk_round_rate() returns long.
