Yes, it looks better.
So, I will modify it as:

config ARCH_NUVOTON
     bool "Nuvoton SoC Family"
     select PINCTRL
     select PM
     select GPIOLIB
     select SOC_BUS
     help
       This enables support for Nuvoton MA35D1 ARMv8 SoC such as MA35D1.

And move PINCTRL_MA35D1 to pinctrl Kconfig when we submit the pictrl 
driver.

Thanks you.
