ACPI: sysfs: Replace sprintf() with sysfs_emit()

ACPI: sysfs: Replace sprintf() with sysfs_emit()

Replace all sprintf() calls with sysfs_emit() in sysfs show functions.

sysfs_emit() is preferred to sprintf() for formatting sysfs output
as it provides better bounds checking and prevents potential buffer
overflows.
