sched/clock: fix CLOCK_BOOTTIME and CLOCK_MONOTONIC handling

Browse source 
The current implementation retrieves time from the same source for both
CLOCK_BOOTTIME and CLOCK_MONOTONIC, which is incorrect. CLOCK_BOOTTIME
includes time spent in system suspend, whereas CLOCK_MONOTONIC does not.

This patch fixes the incorrect clock source handling and ensures the
two clocks are distinguished properly.
