soc/ipq806x : Add CONFIG_TTB_BUFFER for the soc.
Define a base address for page table entries. Place it 64KB below the
bootblock loading address.
BUG=chrome-os-partner:28467
TEST=verified that the page tables are being populated at this
address. Also observed that the SPI driver takes 900 ns to
process a byte as opposed to 1.5 us in case caching is not
enabled.
