Input: ims-pcu - fix printf string overflow

clang warns about a string overflow in this driver

drivers/input/misc/ims-pcu.c:1802:2: error: 'snprintf' will always be truncated; specified size is 10, but format string expands to at least 12 [-Werror,-Wformat-truncation]
drivers/input/misc/ims-pcu.c:1814:2: error: 'snprintf' will always be truncated; specified size is 10, but format string expands to at least 12 [-Werror,-Wformat-truncation]

Make the buffer a little longer to ensure it always fits.
