ARM: SAMSUNG: support the second capability for samsung-soc
In mmc, there are capabilities and use the host_caps. That capability is expressed with bit[0:31]. But now..already filled the bit[0:31]... so we need to denote with the other capability field. (if we want to use the cache, powerclass, etc for eMMC.. this field is necessary) Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Kyungmin Park <Kyungmin.park@samsung.com> Acked-by: Chris Ball <cjb@laptop.org> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
