common/cnxk: ensure ROC cache alignment of NPA stack size

When PLT_CACHE_LINE_SIZE is set to 64B, the memzone size reserved for
NPA stack could be a multiple of 64B. In such a case, when NDC SYNC
is initiated for the NPA LF, it could go and corrupt an additional
64B bytes as NDC flushes in multiples of ROC cache line size (128B).

So ensure that NPA stack size requested is a multiple of 128B.
