power: reset: msm: add support to select both dumps
With Minidump support enabled, user may need to request
to dump both fulldump as well as minidump for debug purpose.
Add support on dload_mode sysfs entry to select both dumps.
Enable both dumps with command:
echo both > /sys/kernel/dload/dload_mode
