Re-engineer the LPAE TTBR setup code. Rather than passing some shifted address in order to fit in a CPU register, pass either a full physical address (in the case of r4, r5 for TTBR0) or a PFN (for TTBR1). This removes the ARCH_PGD_SHIFT hack, and the last dangerous user of cpu_set_ttbr() in the secondary CPU startup code path (which was there to re-set TTBR1 to the appropriate high physical address space on Keystone2.)
