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.
