Fixes#47921
When setting a GPIO to certain value, and then get the GPIO value, on some
platforms, such as ITE, these two values may not be the same. For example
setting GPIO_OUTPUT | GPIO_OUTPUT_INT_HIGH, it will read back
GPIO_OUTPUT | GPIO_OUTPUT_INT_HIGH | GPIO_VOLTAGE_3P3. This is as expected,
as GPIO_VOLTAGE is a read only property. So when comparing the gpio set
and get values, it is necessary to filter the read only bits first and
then compare to the set value.
