OMAP2+: hwmod: allow board files to prevent devices from being reset upon init

Browse source

Some boards can't tolerate IP blocks being reset when they are initialized.
Michael Büsch cites a case with the Nokia N810:

To allow such boards to continue working normally, allow board file
maintainers to mark IP blocks to prevent them from being reset upon
init.  This is done via a hwmod function, omap_hwmod_no_setup_reset().
