[PATCH RFC 5/5] mmc: mmci: move ST specific sdio setup under a condition

[Srinivas Kandagatla]

From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx>

This patch moves ST specific sdio setup under a vendor id condition,
this will ensure that the ST specfic setup is not done on other vendor
like Qualcomm.

Originally the issue was detected while testing WLAN ath6kl on IFC6410
board with APQ8064 SOC.
