From: Arnd Bergmann <arnd@arndb.de>

The only reference to mtk8195_jpegenc_drvdata is inside of an #ifdef:

drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.c:1879:32: error: 'mtk8195_jpegenc_drvdata' defined but not used [-Werror=unused-variable]
 1879 | static struct mtk_jpeg_variant mtk8195_jpegenc_drvdata = {
      |                                ^~~~~~~~~~~~~~~~~~~~~~~

Fix this by just removing the #ifdef and the corresponding
of_match_ptr(). They don't actually serve any purpose here since the
driver is only usable when CONFIG_OF is enabled, and build testing
without that is not a problem.

Fixes: 934e8bccac95 ("mtk-jpegenc: support jpegenc multi-hardware")
