Przemyslaw Stekiel 75df9ecd19 tests-mbed_drivers-lp_ticker: increase tolerance for NRF51_DK
This test fails sometimes while testing 1 ms timeout on NRF51_DK board.
This board is very slow and lp ticker is inaccurate.
I noticed that measured results are very close to the tolerance value. For 1ms delay we measure in failure case 1560 us and tolerance is set to 550.
Since measurement method is also significantly flawed (extra time for setting up ticker and execution of a ticker irq handler) I recommend to increase tolerance by least +100 us for now.
