mmc: s3c6410: add new quirk in sdhci driver and update ADMA descriptor build

The s3c6410 sdhci controller does not support the 'End' attribute and NOP
attribute in the same 8-Byte ADMA descriptor.  This patch adds a new quirk
to identify sdhci host contollers with such behaviour.  In addition to
this, for controllers using the new quirk, the last entry in the ADMA
descritor table is marked with the 'End' attribute (instead of using a NOP
descriptor with 'End' attribute).
