write protect: extract checking write protect
The write-protect state can be checked on 2 pins GPIO_WP or GPIO_WP_L.
The CONFIG_WP_ACTIVE_HIGH config is used to distinguish these two cases.
Move the checking the config and pin state to a separate header file.
For Zephyr, start using the gpio_get_level function that takes into
account the GPIO_ACTIVE_LOW flag. Also, use 'gpio-wp' alias to the WP
pin instead of the legacy enum-name property and 'int-wp' alias to the
WP GPIO interrupt.
BUG=b:211779766
TEST=zmake testall & make sure WP works
