hwmon: (sht15) Root out platform data

Browse source 
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.

sensors. Disabling the reload of those coefficients allows saving 10ms for each
measurement and decrease power consumption, while losing on precision.
Some options may be set directly in the sht15_platform_data structure
or via sysfs attributes.
