[PATCH 6/9] riscv: dts: spacemit: Add pinctrl configurations for PWM0-PWM19

Add pinctrl configurations for PWM0 to PWM19 in the SpacemiT K1
device tree source file. Each PWM instance is assigned multiple
pinmux configurations corresponding to different GPIOs and
function modes.
Configurations include:
- Mapping GPIOs to appropriate pinctrl nodes for PWM functionality
- Specifying bias-pull-up and drive-strength attributes
These updates ensure proper pin multiplexing and drive strength
settings for PWM signals on the SpacemiT K1 SoC when selected.
