Per filesystems/sysfs.rst, show() should only use sysfs_emit()
or sysfs_emit_at() when formatting the value to be returned to user space.

coccinelle complains that there are still a couple of functions that use
snprintf(). Convert them to sysfs_emit().

> ./drivers/fsi/fsi-master-ast-cf.c:1086:8-16: WARNING: please use sysfs_emit
> ./drivers/fsi/fsi-master-gpio.c:721:8-16: WARNING: please use sysfs_emit

No functional change intended
