create_tlb1_entry and create_tlb0_entry creates TLB entries with IPROT bit set by default. Any TLB entries with IPROT = 1 can not be invalidated.
Add IPROT as input argument for TLB entry creation APIs.

NACK as discussed in the thread where you suggested this.
Sigh, didn't notice this was the external list, so I'll elaborate. We never want to create a non-IPROT entry, as we don't have a TLB miss handler that will replace entries that have been invalidated. This will be especially important if we ever run U-Boot inside a virtual machine. And yes, this means that the current TLB0 usage should go away as well.
