This patch currently contains common CAR initialization
required in bootblock phase along with common MSR header -
1. Use SOC_INTEL_COMMON_BLOCK_CAR to have common CAR initialization
and CAR teardown.
2. Use common MSR header "intelblocks/msr.h" inside soc/cpu.h

Add new option to set up Cache-As-RAM by using CQOS, Cache Quality of
Service. CQOS allows setting ways of cache in no-fill mode, while keeping
other ways in regular evicting mode. This effectively allows using CAR
and cache simultaneously.
BUG=chrome-os-partner:51959
TEST=switch from NEM to CQOS and back, boot

The current Apollolake flow has its code executing out of
cache-as-ram for the pre-DRAM stages. This is different from
past platforms where they were just executing-in-place against
the memory-mapped SPI flash boot media. The implication is
that when cache-as-ram needs to be torn down one needs to be
executing out of DRAM since the act of cache-as-ram going
away means the code disappears out from under the processor.
Therefore load and use the postcar infrastructure to bootstrap
this process for tearing down cache-as-ram and subsequently
loading ramstage.
