wifi: rtw88: limit indirect IO under powered off for RTL8822CS
The indirect IO is necessary for RTL8822CS, but not necessary for other
chips. Otherwiese, it throws errors and becomes unusable.
rtw88_8723cs mmc1:0001:1: WOW Firmware version 11.0.0, H2C version 0
rtw88_8723cs mmc1:0001:1: Firmware version 11.0.0, H2C version 0
rtw88_8723cs mmc1:0001:1: sdio read32 failed (0xf0): -110
rtw88_8723cs mmc1:0001:1: sdio write8 failed (0x1c): -110
rtw88_8723cs mmc1:0001:1: sdio read32 failed (0xf0): -110
By vendor driver, only RTL8822CS and RTL8822ES need indirect IO, but
RTL8822ES isn't supported yet. Therefore, limit it to RTL8822CS only.
