[U-Boot] [U-Boot,v2,3/5] rk3288: vyasa: Add TPL support

[Philipp Tomsich]

> From: Jagan Teki <jagan at amarulasolutions.com>
> 
> 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.
