mmc: sdhci-cadence: add Mobileye eyeQ support

Browse Source 
[ Upstream commit 120ffe250dd95b5089d032f582c5be9e3a04b94b ]

The MMC/SDHCI controller implemented by Mobileye needs the preset value
quirks to configure the clock properly at speed slower than HS200.
It otherwise works as a standard sd4hc controller.
