Fix SAI2B pin muxing for AV96 board on STM32MP15.
The label "sai2a-4" is defined twice. Change redundant label to 
"sai2b-4".

Fixes: dcf185ca8175 ("ARM: dts: stm32: Add alternate pinmux for 
SAI2 pins on stm32mp15")

This mp1 pinmuxing is a total mess, sigh.

What is the issue here ?

The same-old discussion about where to place the pinmux nodes, whether 
we should have these clusters of pre-defined options in 
...pinctrl.dtsi, or whether we should do more nxp-like per-board 
configuration.

ok it's a bit more precise. Honestly I don't understand why the current 
topology is an issue here. Maybe pinctrl SAI nodes names are not well 
chosen or are not enough explicit. Concerning our topology and the NXP 
ones both exists and both have advantages and drawbacks. For ST boards 
(DK/EV) we want to keep all configs in the same place.

As I prefer to not re open this topic again and again, feel free to add 
your pin config in your dts board file, I'll accept it.

Yes, let's not reopen it. I'm sorry if my grumbling came across as too 
strong.
