It is standard practice to have a specific board compatible string, so
pass "logicpd,imx6q-logicpd".

Add an entry for imx6q-logicpd.dtb so that it can be built by default.

Using the native SPI chipselect on i.MX6 is known to be problematic.
Doing it on a imx6q-sabresd causes the SPI NOR probe to fail:
[ 5.388704] spi-nor spi0.0: unrecognized JEDEC id bytes: 00 00 00 00 00 00
Use the GPIO chipselect to avoid such problem.

Subject prefix should be 'ARM: dts: imx: ...'
I fixed it up and applied the series.
