spi: replace snprintf in show functions with sysfs_emit

Browse Source 
show() must not use snprintf() when formatting the value to be
returned to user space.

Fix the following coccicheck warning:
drivers/spi/spi-tle62x0.c:144: WARNING: use scnprintf or sprintf.

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
