Subject: [PATCH] mmc: meson-gx: Remove setting of CMD_CFG_ERROR

From: Rong Chen <rong.chen@...ogic.com>

Setting bit CMD_CFG_ERROR has non effects on previous controllers.
However, it will cause an IRQ and stop working on latest controllers,
This bit is used for selecting SG LINK of data address.
Don't set the bit CMD_CFG_ERROR anymore to resolve this issuse.

Therefore, remove this setting.
