[PATCH] Removed legacy data types from arm

[Pavel Pisa]

Hello Vipul Nayyar,

I have weak appeal to not remove rtems_irq_hdl_param
definition from RTEMS headers. It would cause problems
for code which needs to be compatible with more RTEMS
versions.

As for users/functions prototypes, I am not sure, conversion
to (void * ) is OK with me, but on the other hand
rtems_irq_hdl_param documents what is that parameter
and where its value originates.

Best wishes,

                Pavel Pisa
