RTS5261 support SD mode and PCIe/NVMe mode. The workflow is as follows. 1.RTS5261 work in SD mode and set MMC_CAPS2_SD_EXP flag. 2.If card is plugged in, Host send CMD8 to ask card's PCIe availability. 3.If the card has PCIe availability and WP is not set, init_sd_express() will be invoked, RTS5261 switch to PCIe/NVMe mode. 4.Mmc driver handover it to NVMe driver. 5.If card is unplugged, RTS5261 will switch to SD mode.
