[PATCH 1/2] platform/x86/intel/uncore-freq: Replace sprintf() with snprintf()

[Kaushlendra Kumar <kaushlendra.kumar@intel.com>]

Replace unbounded sprintf() calls with snprintf() to prevent potential
buffer overflows when formatting device names. While the current format
strings cannot overflow the buffer, using snprintf() follows kernel
best practices for string formatting.
