linux-gen: timer: add config option to disable usage of 128-bit atomics
On some platforms 128-bit atomic operations may be available, but the
implementation of used 128-bit GCC built-in functions (e.g.
__atomic_compare_exchange_n) utilizes expensive locking. Add implementation
internal config define CONFIG_TIMER_128BIT_ATOMICS for disabling usage of
128-bit atomics in the timer implementation.
