km/common: fix for CPUWD reset reason

km/common: fix for CPUWD reset reason

The CPUWD reset reason is used for kmp204x.
And the qrio cpu reset request is configured to operate in
core reset mode.
But for the evaluation of the qrio's reset reason register
the CPUWD figures as a unit reset source rather than a core
reset source. This patch defines the CPUWD reset as a core
reset source when evaluating the reset reason register.
