clk-si5341: replace snprintf in show functions with sysfs_emit

coccicheck complains about the use of snprintf() in sysfs show functions.

Fix the following coccicheck warning:
drivers/clk/clk-si5341.c:1471: WARNING: use scnprintf or sprintf.
drivers/clk/clk-si5341.c:1486: WARNING: use scnprintf or sprintf.
drivers/clk/clk-si5341.c:1501: WARNING: use scnprintf or sprintf.
drivers/clk/clk-si5341.c:1516: WARNING: use scnprintf or sprintf.

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
