hwmon: (sht15) Root out platform data
After finding out there are active users of this sensor I noticed: - It has a single PXA27x board file using the platform data - The platform data is only used to carry two GPIO pins, all other fields are unused - The driver does not use GPIO descriptors but the legacy GPIO API I saw we can swiftly fix this by: - Killing off the platform data entirely - Define a GPIO descriptor lookup table in the board file - Use the standard devm_gpiod_get() to grab the GPIO descriptors from either the device tree or the board file table. This compiles, but needs testing.
