MMC host controller requires a delay between every sdhci_send_cmd()
execution. In s5p_mmc driver (s5p_sdhci replaces this driver), a delay
of 1000us was provided after every mmc_send_cmd() call. Adding a quirk
in current sdhci driver to replicate the behaviour.
Without this delay, MMC initialization on Origen board fails with
following error messages.
Timeout for status update!
mmc fail to send stop cmd

Some boards have no Card Detect wired. In that case, set the CD test
bits in the standard interface.

To support the Samsung-SoC, added the basically functions.
Samsung-SoC didn't used the SDHCI_CTRL_HISPD.
And added set_control_reg callback for s3c64xx.

When response type is R1b, mask value is added the SDHCI_INT_DAT_END.
but in while(), didn't check that flag.
So sdhci controller didn't work fine.
CMD6 didn't always complete.
So add the quirks for broken r1b response
and add the timeout value to prevent the infinite loop.

sdhci_readw does not work for host version read in Armada100 series
SoCs. This patch fix this issue by making a sdhci_readl call to get host
version.

Nowdays, there are plenty of mmc driver in uboot adopt the sd standard
host design, aka as sdhci. It is better to centralize the common logic
together to better maintenance.
