tools/cpupower: Choose base_cpu to display default cpupower details
The default output of cpupower info utils shows unexpected output
when CPU 0 is disabled.
Considering a case where CPU 0 is disabled, output of cpupower idle-info:
Before change:
cpupower idle-info
CPUidle driver: pseries_idle
CPUidle governor: menu
analyzing CPU 0:
*is offline
After change:
./cpupower idle-info
CPUidle driver: pseries_idle
CPUidle governor: menu
analyzing CPU 50:
Number of idle states: 2
Available idle states: snooze CEDE
snooze:
Flags/Description: snooze

CEDE:

If -c option is not passed, CPU 0 was chosen as the default chosen CPU to
display details. However when CPU 0 is offline, it results in showing
unexpected output. This commit chooses the base_cpu
instead of CPU 0, hence keeping the output more relevant in all cases.
The base_cpu is the number of CPU on which the calling thread is
currently executing.
