Since Pygments 2.7.0 devicetree syntax is supported, so there is no need
to use a custom lexer. Version 2.9.0 introduces a fix that is required
for some devicetree snippets.

This patch removes sdhc_api references since such API
does not actually exist. SD card controller drivers
use disc driver interface. Accordingly, the SDHC documentation,
which actually describes how to connect a SD card via SPI
and has little to do with SD host controller (SDHC),
is also moved to disk access page and adapted.
