[U-Boot] mmc: sdhci: Add a quirk to add delay during completion of sdhci_send_cmd

Hi,

I saw that you have been added the SDHCI_QUIRK_WAIT_SEND_CMD on below commit http://git.denx.de/?p=u-boot.git;a=commitdiff;h=13243f2eafc4292917178051fe1b...

I need few quires regarding the QUIRK delay. 1. Why the delay is 1000 + if (host->quirks & SDHCI_QUIRK_WAIT_SEND_CMD) + udelay(1000); + 2. is this delay specific to s5p_sdhci controller? 3. I have an issue "Controller never released inhibit bit(s)" but when I enable this quirk on my driver with udelay(10000), it's working.

Could you please help me.

Thanks, Jagan.
