[PATCH] imx91: fix pinmux macros for ENET1_TD3 and I2C2_SCL

[Francesco Valla]

Fix macros for the GPIO function for two pads (ENET1_TD3 and I2C2_SCL),
aligning them to the functions specified in the datasheet.

Fixes: a9d562daa3c3 ("imx: Add iMX91 support")

Part of this patch was initially sent under a different commit message,
[1] but was then completed with another related bugfix (thanks Javier).
I decided to merge the two because they can be seen as targeted to the
same purpose: proper support of OF_UPSTREAM for any device based on the
i.MX91 SoC.

Since the content is changed, I dropped the R-b tag by Fabio (hoping it
can be gained also for this version).

Thank you!

Regards,
Francesco
