media: raspberrypi: Switch to remove_new

The remove callback's return value is about to change from int to void,
this is done by commit 0edb555a ("platform: Make
platform_driver::remove() return void"). Prepare for merging the patch by
switching the PiSP driver from remove to remove_new callback.

Fixes: 12187bd5 ("media: raspberrypi: Add support for PiSP BE")
