ARCv2 cores may have built-in SLC (System Level Cache, AKA L2-cache). This change adds functions required for controlling SLC:

• slc_enable/disable
• slc_flush/invalidate

For now we just disable SLC to escape DMA coherency issues until either:

• SLC flush/invalidate is supported in DMA APIin U-Boot
• hardware DMA coherency is implemented (that might be board specific so probably we'll need to have a separate Kconfig option for controlling SLC explicitly)

Applied, thanks.
