[PATCH v2 1/1] mfd: stmpe: Allow building as module

[Alexander Stein]

Export the core probe and remove function to be used by i2c and spi
drivers. Also add necessary module information so the drivers can be built
as modules. This reduces footprint of the driver is enabled but unused.

Changes in v2:
* Improved commit message
* Remove superfluous text from module description
* Patch 1/3 and 2/3 already applied in next-20250819
