Reset cause indication for MCWDT

If the MCWDT counter is not serviced or serviced too early, a system reset can be issued after the FAULT is not
handled in time. When the device comes out of reset, it is useful to know the cause of the reset. Reset causes
are recorded in the RES_CAUSE register. Depending on the MCWDT instance used, the reset event is stored in
the RESET_MCWDT0[5], RESET_MCWDT1[6], RESET_MCWDT2[7], and RESET_MCWDT3[8] bits in the RES_CAUSE
register. The bits in the RES_CAUSE register are set on the occurrence of the corresponding reset and remain
set until cleared by the user software or a power-on reset (POR).
