This patch add test mode for RTS5261.
If test mode is set, reader will switch to SD Express mode
mandatorily, and this mode is used by factory testing only.

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.

Add support for new chip rts5261.
In order to support rts5261, the definitions of some internal registers
and workflow have to be modified and are different from its predecessors.
So we need this patch to ensure RTS5261 can work.
