Add IPROT as input argument for TLB entry creation APIs.

Based upon git://git.denx.de/u-boot.git branch master
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.
oh..
this means function like invalidate_tlb(1) should not be used u-boot?
Pretty much, yes.
