[PATCH v4 0/2] add gpmi support for imx6q

This patch set adds the gpmi-nand support for imx6q.

I prefer to add the clocks in the gpmi-nand driver.
Yes, it will change the gpmi nand driver, but we have to do so.
The reason is :
  We will support the ONFI nand in mx6q in the future. If the ONFI nand is
  set to Sync mode, we have to __change__ the clocks explicitly.

Test this patch set on imx6q-arm2 board and imx28-evk board.

v3 --> v4:
	[1] add con_id for gpmi nand
	[2] balance the clk_prepare_enable()/clk_disable_unprepare()
	    in __gpmi_enable_clk();
	[3] do not send the second patch which is applied to Shawn's tree.

v2 --> v3:
	[1] fix a bug the clocks.

v1 --> v2:
	[1] add dev_id for the gpmi-nand's clocks.
	[2] set the default values for these clocks.
