mmc: exynos_dw_mmc: Move quirks from struct dwmci_host to chip data

host->quirks field is only used internally in exynos_dw_mmc.c driver.
To avoid cluttering the scope of struct dwmci_host, move quirks field
into Exynos driver's chip data, where it can be statically defined.

No functional change.
