hwmon: Support Aspeed AST2600 PWM/Fan tachometer

Add Aspeed AST2600 PWM/Fan tacho driver. AST2600 has 16 PWM channel and 16 FAN tacho channel. Changes since v1: - fixed review comments - fixed double-looped calculation of div_h and div_l - moving configuration to device tree - register hwmon driver with devm_hwmon_device_register_with_info() Signed-off-by: Troy Lee <troy_lee@aspeedtech.com>
