arm/{bcm2835,fsl-imx25,fsl-imx6}: Fix realize error API violations

The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

bcm2835_peripherals_realize(), fsl_imx25_realize() and
fsl_imx6_realize() are wrong that way: they pass &err to
object_property_set_uint() and object_property_set_bool() without
checking it, and then to sysbus_realize().  Harmless, because the
former can't actually fail here.

Fix by passing &error_abort instead.
