pwm: meson: Read the full hardware state in meson_pwm_get_state()
Update the meson_pwm_get_state() implementation to take care of all information in the registers instead of only reading the "enabled" state. The PWM output is only enabled if two conditions are met: 1. the per-channel clock is enabled 2. the PWM output is enabled Calculate the PWM period and duty cycle using the reverse formula which we already have in meson_pwm_calc() and update struct pwm_state with the results. As result of this /sys/kernel/debug/pwm now shows the PWM state set by the bootloader (or firmware) after booting Linux.
