MIPS: intel: add initial support for Intel MIPS SoCs

This patch series is for adding the support for Intel MIPS interAptiv SoC GRX500 family. It includes CCF support, serial driver optimization and DTS modification.

This patch series is applied on top of linux v4.18-rc7. Basic verification is performed on GRX500 board.

We propose merging this patch series into MIPS Linux tree.

Changes in v2:
- Remove unused _END macros
- Remove the redundant check and not accurate comments
- Replace the get_counter_resolution function with fixed value 2
- Use obj-y and split into per line per .o
- Add EVA mapping description in code comments
- Remove unused include header file
- Do a clean-up for grx500_defconfig
- Rewrite clock driver, add platform clock description details in clock driver.
- Rewrite clock driver's dt-binding document according to Rob Herring's comments.
- Simplify device tree docoment, remove some clock description.
- New patch split from previous patch
- The memory address is changed to @20000000
- Update to obj-$(CONFIG_BUILTIN_DTB) as per commit fca3aa166422
- New patch split from previous patch
- Add the board and chip compatible in dt document
- New patch to reorder the head files according to the coding style.
