Log message:
Fix some correctness issues in the lowelevel kernel bringup code.
- Make sure we install a dummy page table in TTBR0_EL1 before we change
the size of the VA space in TCR_EL1.
- Flush the TLB after updating TCR_EL1.
- Flush TLB after installing the real kernel page table in TTBR1_EL1.
- Add some barriers around TLB flushes to make it consistent with
other places where we do TLB flushes.
