Usually when the kernel becomes too large we don't see any output
on the console at all. That's because the decompressor overwrites
something like the dtb or the initrd when it uncompresses the
kernel and then serial console can't be found. In this case, it
looks like it booted up and then got stuck when trying to run
/init from the ramdisk? Or maybe it got stuck in some interrupt
storm with mmc? There are some regulator warnings that seem to be
ignored earlier for the mmc.

[    2.252965] s4: voltage operation not allowed
[    2.258505] mmci-pl18x 12400000.sdcc: Voltage switch failed

No idea if that forebodes doom though.
