crypto: octeontx2 - CN10K CPT to RNM workaround
When software sets CPT_AF_CTL[RNM_REQ_EN]=1 and RNM in not producing entropy(i.e., RNM_ENTROPY_STATUS[NORMAL_CNT] < 0x40), the first cycle of the response may be lost due to a conditional clocking issue. Due to this, the subsequent random number stream will be corrupted. So, this patch adds support to ensure RNM_ENTROPY_STATUS[NORMAL_CNT] = 0x40 before writing CPT_AF_CTL[RNM_REQ_EN] = 1, as a workaround.
