Revert "boards/esp32s3-xiao: switch defconfigs to nxinit entrypoint"

Browse source 
This reverts commit 7cc6707a76.

Felipe Moura de Oliveira reported on the dev mailing list that this
commit hangs boot on real Seeed XIAO ESP32-S3 Sense hardware (chip
rev v0.2): both defconfigs (combo, usbnsh) never reach nx_start after
a normal reset (no console output, no USB enumeration; only ROM
download mode via the BOOT strap pin responds). JTAG (OpenOCD + GDB)
shows the core statically stuck inside the chip boot ROM address
range (0x40034000-0x40048000), with nx_start never reached at its
own address (0x42011068) in that build. Reverting only this commits
defconfig changes on top of current master fixes the boot.

Local static analysis (before/after build product comparison via
esptool image_info and readelf -S) ruled out image size/segment
count as the cause: both binaries have 3 segments, identical IRAM
segment address/size byte-for-byte, and the flash-mapped code/data
growth from this change is ~14.7KB total against an 8MB flash
budget. No hardware matching the reported board was available
locally to reproduce or bisect further; reverting to unblock master
per the reporters request while root cause is investigated with
real hardware access.
