can: janz-ican3: fix support for older hardware revisions
commit e21093ef6fb4cbecdf926102286dbe280ae965db upstream.
The Revision 1.0 Janz CMOD-IO Carrier Board does not have support for
the reset registers. To support older hardware, the code is changed to
use the hardware reset register on the Janz VMOD-ICAN3 hardware itself.
