[i.MX] various errors in arch/arm/boot/dts/imx*-pinfunc.h files

[Lothar Waßmann]

Hi,

after finding a bug in the imx6ul-pinconf.h file (missing input_sel
config for MX6UL_PAD_UART5_RX_DATA__ECSPI2_MISO), I decided
to write a perl script (see attachment) to check the file for
consistency and found 44 more errors in the same file.

Running the script over the remaining imx pinconf files revealed the
following errors:

I will send a patch for imx6ul and imx51 shortly.
But I have no resources to correct the bugs in the imx35, imx50 and
imx7d files.
The "Duplicate MUX reg addr" message for imx7d are false positives due
to the deviant nature of the imx7d pinctrl design, but the other
messages should be relevant.
