Subject: [PATCH] mmc: sdio_cis: fix unknown tuple for CISTPL_SDIO_STD

CISTPL_SDIO_STD(0x91) is a known tuple, but sdio_cis didn't define it,
so we get the warning blow while probing several sdio wifi. Refer to SDIO spec,
it's no need to parse the tuple, so this patch just make it a known one.

[    4.098980] mmc2: queuing unknown CIS tuple 0x91 (3 bytes)
[    4.099033] mmc2: new ultra high speed SDR104 SDIO card at address 0001
