mmc: atmel-mci: Fix debugfs on 64-bit platforms

"atmel_mci.pending_events" and "atmel_mci.completed_events" are
"unsigned long", i.e. 32-bit or 64-bit, depending on the platform.
Hence casting their addresses to "u32 *", and calling
debugfs_create_x32() breaks operation on 64-bit platforms.

Fix this by using the new debugfs_create_xul() helper instead.
