soc/intel/skylake: Add SGX initialization
This patch implements SGX initialization steps in coreboot per Intel SGX
BWG rev 2.0.8 for Kaby Lake SoC. If enabled on a Kabylake device, SoC
capability and PRM (processor reserved memory) of desired size (needs to
be configured through PrmrrSize) are provisioned for later software
stack to use SGX (i.e., run SGX enclaves).
One issue is still puzzling and needs to be addressed: by calling
configure_sgx() in cpu_core_init() which is the per-thread function, SGX
is always failing for thread 0 but is successful for other 3 threads.
I had to call configure_sgx() again from soc_init_cpus() which is the
BSP-only function to make it enable on the BSP.
Another pending work is the implementation for the Owner Epoch update
which shall be added later.
BUG=chrome-os-partner:62438
BRANCH=NONE
TEST=Tested on Eve, verified SGX activation is successful on all threads.
