sh: Fix up extended mode TLB for SH-X2+ cores.
The extended mode TLB requires both 64-bit PTEs and a 64-bit pgprot, correspondingly, the PGD also has to be 64-bits, so fix that up. The kernel and user permission bits really are decoupled in early cuts of the silicon, which means that we also have to set corresponding kernel permissions on user pages or we end up with user pages that the kernel simply can't touch (!). Finally, with those things corrected, really enable MMUCR.ME and correct the PTEA value (this simply needs to be the upper 32-bits of the PTE, with the size and protection bit encoding).
