MLK-10674-2 imx: mx6qp settings for PRE
Since the following piece settings can not be in DCD table, we
add them in enable_ipu_clock.

setmem /32 0x00bb048c = 0x00000002 ## Bypass IPU1 QoS generator
setmem /32 0x00bb050c = 0x00000002 ## Bypass IPU2 QoS generator
setmem /32 0x00bb0690 = 0x00000200 ## Bandwidth THR for of PRE0
setmem /32 0x00bb0710 = 0x00000200 ## Bandwidth THR for of PRE1
setmem /32 0x00bb0790 = 0x00000200 ## Bandwidth THR for of PRE2
setmem /32 0x00bb0810 = 0x00000200 ## Bandwidth THR for of PRE3
setmem /32 0x00bb0694 = 0x00000020 ## Saturation THR for of PRE0
setmem /32 0x00bb0714 = 0x00000020 ## Saturation THR for of PRE1
setmem /32 0x00bb0794 = 0x00000020 ## Saturation THR for of PRE2

CONFIG_VIDEO_IPUV3 is always defined in mx6sabre_common.h,
the settings sure will effect.
