arm: dts: omap: Mark various register maps as dangerous

These register maps contain registers where reads can cause an
imprecise async data abort.
Mark these register maps with has-inaccessible-regs to make sure
they cannot be accessed via debugfs and only by device drivers that
hopefully know exactly how and when access is allowed.
