* According to DW Mobile Storage databook it is required

* 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.
