drm/repaper: fix -Wvoid-pointer-to-enum-cast warning

When building with clang 18 I see the following warning:
|       drivers/gpu/drm/tiny/repaper.c:952:11: warning: cast to smaller integer
|       type 'enum repaper_model' from 'const void *' [-Wvoid-pointer-to-enum-cast]
|         952 |                 model = (enum repaper_model)match;
|

This is due to the fact that `match` is a void* while `enum repaper_model`
has the size of an int.

Add uintptr_t cast to silence clang warning while also keeping enum cast
for readability and consistency with other `model` assignment just a
few lines below:
|       model = (enum repaper_model)spi_id->driver_data;
