/**
* @brief Verify partition data
*
* Given a pointer to partition data, verify this partition exists in the partition table (all fields match.)
*
* This function is also useful to take partition data which may be in a RAM buffer and convert it to a pointer to the
* permanent partition data stored in flash.
*
* Pointers returned from this function can be compared directly to the address of any pointer returned from
* esp_partition_get(), as a test for equality.
*
* @param partition Pointer to partition data to verify. Must be non-NULL. All fields of this structure must match the
* partition table entry in flash for this function to return a successful match.
*
* @return
* - If partition not found, returns NULL.
* - If found, returns a pointer to the esp_partition_t structure in flash. This pointer is always valid for the lifetime of the application.
