Since the size of SPL can't be exceeded 0x8000 bytes in RK3288, it is not possible add new SPL features like Falcon mode or etc.
So add TPL stage so-that adding new features to SPL is possible.
- TPL: DRAM init, clocks
- SPL: MMC, falcon, etc

Changes for v2:
- Drop console output from commit message
- Updated licence note
- Moved read/write L2CTRL and configure_l2ctlr to common
- Moved debug header in include files list
- Moved preprocessor macro to top
Note: Idea is not to build this in SPL when TPL enabled, so CONFIG_SUPPORT_TPL work that case.
