Add section to clear SPL & Uboot to use SDcard for data storage

SD card: It is generally not possible to boot from eMMC to partition the unmounted SD card, because of the boot order -- you would have to write the image to the empty SD card first, then resize partition, all without rebooting. It is also '''not recommended''' to resize the SD card while booted from SD card! Resizing a currently mounted partition can have weird results.

== Reuse SD card for data storage on system booting from eMMC==
Once you have installed your release of choice to eMMC, you may wish to use an SD card for data storage. If you choose to re-use a card you have previously used to boot from, you will find your phone will not boot if you just reformat the card and insert it. This is because the Allwinner firmware in the PinePhone uses some (normally) unused space at the front of the SD card to store boot software, which you need to clear.
This can be done as follows on any linux system:
lsblk
to check the device of your SD card – as an example lets assume it is /dev/mmcblk0
then
sudo dd if=/dev/zero of=/dev/mmcblk0 bs=8k seek=1 count=4
will clear the relevant sectors of your card.
