mmc: sdhci-of-at91: use SDHCI_QUIRK2_NEED_DELAY_AFTER_INT_CLK_RST quirk
The Atmel sdhci device needs the SDHCI_QUIRK2_NEED_DELAY_AFTER_INT_CLK_RST quirk. Without it, the internal clock could never stabilised when changing the sd clock frequency. Signed-off-by: Ludovic Desroches <ludovic.desroches@atmel.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
