mmc: sdhci-msm: Use maximum possible data timeout value
The Qcom SD controller defines the usage of 0xF in data timeout counter register (0x2E) which is actually a reserved bit as per specification. This would result in maximum of 21.26 secs timeout value. Some SDcard taking more time than 2.67secs (timeout value corresponding to 0xE) and with that observed data timeout errors. So increasing the timeout value to max possible timeout.
