[PATCH net-next v2 1/2] net: ti: icssg: Add static_assert to guard stat array counts

[MD Danish Anwar]

Place static_assert() immediately after each of icssg_all_miig_stats[]
and icssg_all_pa_stats[] in icssg_stats.h to verify at build time that
ICSSG_NUM_MIIG_STATS and ICSSG_NUM_PA_STATS stay in sync with the
actual array sizes. This turns a silent miscount into a build error
should either the constant or the array be updated independently.
