hal: Fix systimer counter value bit field

Browse Source 
This commit fixes the systimer_counter_value_t by adding a resreved field so that the
type fills 64-bits.

Without the reserved field, when compiling with -O0 optimization, the unoccupied high
bits would not be initalized by the compiler, leading to systimer_hal_get_counter_value()
returning a garbage value.
