Jisheng Zhang ca1219c0a7 mmc: sdhci-of-dwcmshc: fix rpmb access ... Commit a44f7cb937 ("mmc: core: use mrq->sbc when sending CMD23 for RPMB") began to use ACMD23 for RPMB if the host supports ACMD23. In RPMB ACM23 case, we need to set bit 31 to CMD23 argument, otherwise RPMB write operation will return general fail. However, no matter V4 is enabled or not, the dwcmshc's ARGUMENT2 register is 32-bit block count register which doesn't support stuff bits of CMD23 argument. So let's handle this specific ACMD23 case. From another side, this patch also prepare for future v4 enabling for dwcmshc, because from the 4.10 spec, the ARGUMENT2 register is redefined as 32bit block count which doesn't support stuff bits of CMD23 argument.
