Adolfo Delorenzo 6c6940afac rpi: add boot diagnostics and remove quiet for debugging ...

Remove 'quiet' from RPi cmdline.txt so kernel probe messages are
visible on HDMI. Add comprehensive diagnostics to the data device
error path: dmesg for MMC/SDHCI/regulators/firmware, /sys/class/block
listing, and error message scanning. This will reveal why zero block
devices appear despite all kernel configs being correct.
