[PATCH 0/2] arm64: dts: imx93-11x11-frdm: some fixes

[Maud Spierings via B4 Relay]

pcf2131 has been assigned the rtc0 alias, but if the bbnsm_rtc gets
probed first it will take this name.

Properly assign bbnsm_rtc to rtc1 so that this doesn't happen

Add the power supply to the pcal6408 gpio expander, it doesn't have the
dependency loop like the pcal6524.

On a side note, I'm seeing:

[   16.109866] fec 42890000.ethernet: Using random MAC address: 4e:1b:bb:80:4c:90

But I'm not actually getting a random MAC address, it is constently:
f6:32:43:09:2e:b7

Something off about the nvmem reading or something?

I am also consistently getting crashes on this next tag, also without my
changes:
