arm64: proton-pack: use sysfs_emit in sysfs show functions

Browse source

Replace sprintf() with sysfs_emit() in sysfs show functions, which is
preferred for formatting sysfs output because it provides safer bounds
checking.

While the current code only emits fixed strings that fit easily within
PAGE_SIZE, use sysfs_emit() to follow secure coding best practices.
