Fix an issue in the reset code. Since this code is copied to the reset vector, using 'j' for looping is not correct. Use relative branch 'b'. Update the usage of 'j' in smpboot.S to be consistent although it is not a bug there.

Add SWIOTLB config option and related files to Netlogic platform. Some XLP SoC components like the SD/MMC interface cannot do DMA beyond 32-bit physical address.
