mmc: sdhci: Introduce max_timeout_count variable in sdhci_host
Introduce max_timeout_count variable in the sdhci_host structure
and use in timeout calculation. By default its set to 0xE
(max timeout register value as per SDHC spec). But at the same time
vendors drivers can update it if they support different max timeout
register value than 0xE.
