drivers: fix sprintf with snprintf

Browse Source 
sprintf function is not secure as it doesn't check the length of string.
More secure function snprintf is used

Fixes: 828d51d8fc ("bus/fslmc: refactor scan and probe functions")
Fixes: c22fab9a6c ("raw/dpaa2_qdma: support configuration APIs")
Fixes: e5cbdfc537 ("crypto/dpaa2_sec: add basic operations")
Fixes: b23d4e898a ("crypto/dpaa2_sec: add per dev mempool to store FLE")
Fixes: 623326dded ("crypto/dpaa2_sec: introduce poll mode driver")
Fixes: e7a45f3cc2 ("crypto/caam_jr: add UIO specific operations")
Fixes: f44bccadd8 ("crypto/caam_jr: add device basic operations")
Fixes: 7e3e2954e0 ("crypto/dpaa_sec: move mempool allocation to config")
Fixes: c3e85bdcc6 ("crypto/dpaa_sec: add crypto driver for NXP DPAA platform")
