ARM: Fix get_cycles() after delay_read_timer() conversion
After commit dfc256dac54c ("calibrate: Rework delay timer calibration"),
certain ARM configurations (such as multi_v5_defconfig) hang during
boot. The use of read_current_timer() in arch/arm's get_cycles() was
improperly converted to delay_read_timer(), resulting in get_cycles()
returning 0 even when the timer has been read or an uninitialized stack
value when delay_read_timer() returns false.
Flip the branches of the ternary condition to fix get_cycles().
Fixes: dfc256dac54c ("calibrate: Rework delay timer calibration")
