ENGR00289406-1 mmc: sdhci: add quirk for get max timeout counter
The max timeout counter of some SoCs like i.MX6 uSDHC may not be standard,
add SDHCI_QUIRK2_NOSTD_TIMEOUT_COUNTER quirk to get the correct max timeout
counter from platform specific code.
Then we can calculate the correct max_discard_to value.
