soc/intel/elkhartlake: Do initial SoC commit till ramstage

Clone entirely from Jasperlake

List of changes on top off initial jasperlake clone
1. Replace "Jasperlake" with "Elkhartlake"
2. Replace "jsl" with "ehl"
3. Replace "jsp" with "mcc"
4. Rename structure based on Jasperlake with Elkhartlake
5. Clean up upd override in fsp_params.c will be added later
6. Sort #include files alphabetically as per comment
7. Remove doc details from espi.c until it is ready
8. Remove pch_isclk & camera clocks related codes
9. Add new #define NMI_STS_CNT & NMI_EN as per comment
