[PATCH 1/2] ARM: dts: imx7d-mba7: Remove unsupported property

From: Fabio Estevam <festevam@gmail.com>
Date: 2021-03-03 16:23:56 

'disable-gpio' is not a valid property according to
Documentation/devicetree/bindings/pci/fsl,imx6q-pcie.txt.

Remove the unsupported property.

This is a remnant of linux-imx, which supports the property. On the
MBa7x (and likely other boards in linux-imx that use this), the GPIO is
connected to mPCIe pin 20 (wireless_disable#). Is there an intended way
to control this pin, or should it just be left unconfigured or hogged?

power-on-gpio seems to be obsolete too, I can't even find it in current
linux-imx, except for one other i.MX7D-based DTS. I can send a patch to
remove that as well, but it might take a while until I get to it.

Fabio,

While we are at it, could you resend to include 'power-on-gpio' cleanup
as well?

Shawn
