mmc: sdhci-msm: Use maximum possible data timeout value

The MSM SDHCI 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
5.3 secs timeout value. For some buggy SD cards, the core
layer wants to set the data timeout to 3 secs and on our MSM
SDHCI if we configure data timeout counter value to 0xE,
then we would get only 2.67 secs. Observed data timeout errors
for CMD25 on SDR104 card. Hence program data timeout counter to
0xF, to achieve at least 3 secs timeout value.
