From: Fabio Estevam <fabio.estevam at freescale.com>
In case the bootloader has incorrectly configured the ALT mode of
MX6SL_PAD_ECSPI1_SS0 pad, we end up with the following probe error:
m25p80 spi0.0: found mr25h256, expected m25p32
m25p80 spi0.0: mr25h256 (32 Kbytes)
In order to avoid this issue, add an entry for MX6SL_PAD_ECSPI1_SS0 pad, so
that kernel configures the ECSPI chip select as GPIO functionality, which
results in correct SPI NOR probe.
