linux: add support of Synopsys ARCHS38-based boards This patch introduces support of new boards with ARC HS38 cores. ARC HS38 is a new generation of ARC cores which utilize ARCv2 ISA. As with ARC770 we're addind support for 2 boards for now: [1] Synopsys SDP board (AXS103) This is the same base-board as in AXS101 but with FPGA-based CPU-tile where ARCHs38 core is implemented. [2] nSIM Again this is the same simulation engine but configured for new instruction set and features of new CPU.

* According to DW Mobile Storage databook it is required
* to use "Hold Register" if card is enumerated in SDR12 or
* SDR25 modes.
*
* Utilization of "Hold Register" is already implemented via
* dw_mci_pltfm_prepare_command() which in its turn gets
* used through dw_mci_drv_data->prepare_command call-back.
* This call-back is used in Altera Socfpga platform and so
* we may reuse it saying that we're compatible with their
* "altr,socfpga-dw-mshc".
*
* Most probably "Hold Register" utilization is platform-
* independent requirement which means that single unified
* "snps,dw-mshc" should be enough for all users of DW MMC once
* dw_mci_pltfm_prepare_command() is used in generic platform
* code.
