The imx6sx usdhc is derived from imx6sl, the difference is minor.
imx6sx have the errata ESDHC_FLAG_ERR004536 fixed.
So introduce a new compatible string for imx6sx to distinguish them.

Using specific compatible string in binding doc to make the binding
more clear.
It's also used to avoid checkpatch warning in the future like follows:

The uSDHC has an ADMA Length Mismatch errata ERR004536 which may
cause ADMA work abnormally. The errata has already been fixed for
i.MX6Q TO1.2 and i.MX6DL TO1.1 by enable the bit 7 in 0x6c register.
Unfortunately this fix is not included in i.MX6SL.
So we disable ADMA for i.MX6SL and use SDMA
Patch 1 is a small clean up.
Patch 2-4 and 6 are small fixes.
Patch 5 add mx6sx support.

The iMX6Q/DL can not support HS200 mode while iMX6SL and iMX6SX can,
so introduce a new flag to distinguish them.

The usdhc does not have missing card interrupt issue, so don't execute
workaround for usdhc.

In esdhc_writel_le() function, there's duplicated checking of the same
register as follows:
if (unlikely(reg == SDHCI_INT_ENABLE || reg == SDHCI_SIGNAL_ENABLE)).
Merge them into one and remove the duplicated one.

OK, sounds good. I have some old version of the DesignWare TRM, so
possibly something is different in the newer one...
