Merge branch 'omap/omap2-cleanup' of https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc into arm/soc

Browse Source 
While going through the removal of board files on some other
platforms, I noticed a bit of outdated code on omap2+ that
was left behind after the platform became DT only.

This is a separate branch, to avoid conflicts with other omap2
changes.

* 'omap/omap2-cleanup' of https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc:
  ARM: omap2: make functions static
  ARM: omap2: remove unused omap2_pm_init
  ARM: omap2: remove unused declarations
  ARM: omap2: remove unused functions
  ARM: omap2: smartreflex: remove on_init control
  ARM: omap2: remove APLL control
  ARM: omap2: simplify clock2xxx header
  ARM: omap2: remove unused omap_hwmod_reset.c
  ARM: omap2: remove unused headers
  ARM: omap2: remove unused USB code
  ARM: remove CONFIG_UNUSED_BOARD_FILES

Most ATAGS based board files are completely unused and are
scheduled for removal in early 2023, and left out of kernels
by default now. If you are using a board file that is marked
as unused, turn on this option to build support into the kernel.
To keep support for your individual board from being removed,
send a reply to the email discussion at
