[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/2039925

[Impact]

Missing Realtek RTS5264 SD 7.0 cardreader support:
```
$ lspci -nnnk
0000:56:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device [10ec:5264] (rev 01)
        Subsystem: Dell Device [1028:0cc8]
        Kernel driver in use: rtsx_pci
        Kernel modules: rtsx_pci
```

[Fix]

V4 patchset under review:
https://patchwork.kernel.org/project/linux-mmc/patch/bf45a73f01cc43669dc3796ccff25598@realtek.com/

[Test Case]

With kernel driver probed and loaded successfully, there should be a line in the
dmesg:
```
rtsx_pci 0000:56:00.0: enabling device (0000 -> 0002)
```

[Where problems could occur]

New hardware, expecting all possible way to go wrong.
