ARC: [plat-hsdk] initial port for HSDK board This initial port adds support of ARC HS Development Kit board with some basic features such serial port, USB, SD/MMC and Ethernet. Essentially we run Linux kernel on all 4 cores (i.e. utilize SMP) and heavily use IO Coherency for speeding-up DMA-aware peripherals. Note as opposed to other ARC boards we link Linux kernel to 0x9000_0000 intentionally because cores 1 and 3 configured with DCCM situated at our more usual link base 0x8000_0000. We still can use memory region starting at 0x8000_0000 as we reallocate DCCM in our platform code. Note that PAE remapping for DMA clients does not work due to an RTL bug, so CREG_PAE register must be programmed to all zeroes, otherwise it will cause problems with DMA to/from peripherals even if PAE40 is not used.
