[PATCH v4 1/9] arm64: Set the safe value for L1 icache policy

Right now we use 0 as the safe value for CTR_EL0:L1Ip, which is not defined at the moment. The safer value for the L1Ip should be the weakest of the policies, which happens to be AIVIVT. While at it, fix the comment about safe_val. Cc: Mark Rutland Cc: Catalin Marinas
