Update the document to use standardized section headers as per sphinx
documentation:

The OSPI section wasn't properly enumerated as '3.1.1.11.2.1' as first
the subsection under 'Extra Configuration'.

This patch moves the ifconfig guards to inside of the subsection header
so it's parsed properly.

In OSPI boot with falcon mode, the 'mmcdev' variable is used to select
between SD/MMC or eMMC for loading the fitImage which wasn't documented
previously.

A figure[1] in reStructuredText allows us to easily add a title to GIF,
use that instead of image.

The fitImage is expected to contain the required DTB in falcon mode so
remove the ask for redundant DTB in rootfs from the docs.

I fixed the issues but there are still quite a few false positives in the vale output. The listed errors are because of vale detecting the section markers ======= as git merge conflict markers, among other issues like warning on the mis-spelled fitImage, defconfig etc.

I have no idea if we want to squash these together before we merge but the content looks great
