Make it possible to use UART3 as early debug output, with the associated clock and pinmux configuration. Two sets of output pins are supported (M0/M1). Future users should also note that the pinmux default in the dts is to use the M1 pins while the Kconfig option takes M0 as a default.

The previous chips than RK3288 did not support polarity, and register layout was different from the RK3288 PWM. The RK3288 keep the current functions. RK3328 and the chips after it, which can support hardware lock, configure duty, period and polarity at next same period, to prevent the intermediate temporary state.
