hw/arm: Replace TABs for spaces in OMAP board and device code

In hw/arm and include/hw/arm, some source files for the OMAP SoC
and the sx1 boards that are our only remaining OMAP boards still
have hard-coded tabs (almost entirely used for the indent on
inline comments, not for actual code indent).

Replace the tabs with spaces using vim :retab. I used 4 spaces
except in some defines and comments where I tried to put
everything aligned in the same column for better readability.

This commit is a purely whitespace-only change.
