cgtqmx6eval: fix pad configuration for SPI bus

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().
