Use the macro SETUP_IOMUX_PAD(...) rather than
imx_iomux_v3_setup_multiple_pads(...) in order to setup
the pin configuration for ECSPI1.
ARRAY_SIZE(pads) provides the wrong size for
imx_iomux_v3_setup_multiple_pads(pads, ARRAY_SIZE(pads)) in
case of MX6QDL. In the particular case, the content of GPR12 is overwritten and
the IPG/AHB/ATB/ATP clocks
are deactivated. Therefore, the connection to the system via JTAG is not
possible anymore. Furthermore,
kernel version 3.0.35 hangs during bootprocess in the function etm_init().
