[PATCH 4/6] crypto/dpaa2_sec: increase ivsize range for AES-CTR

Widen the AES-CTR IV size range from the fixed 16-byte value to
[12, 16] with a 4-byte increment. This allows 96-bit IVs (the
standard NIST SP 800-38A recommendation) in addition to 128-bit
IVs, aligning with common usage and test-vector expectations.

The change applies to both dpaa2_sec_capabilities and
dpaa2_pdcp_capabilities.
