tests-mbed_hal-common_tickers: use low level ticker API for time measuring. ...

In `ticker speed` test case execution time of ticker API functions is measured using Timer object. Test replaces original ticker handler for testing purposes, so test should not relay on higher level ticker based features(like Timer).
Use low level ticker API for time measuring.

does not have Ethernet. Removed the check for device emac from emac

Makes Greentea TCP test cases to timeout less in connection errors ...

Made to prevent timeout if a single test case fails. The goal is that
each test case might wait only half of the remaining time reserved for
running TCP test cases.

Fix some targets fail to pass ticker overflow test ...

In mbed-os-tests-mbed_hal-common_tickers/Microsecond ticker overflow test, some targets
would fail to catch specified ticker value near overflow in time and so fail. This commit
alleviates the issue by checking ticker value range rather than one exact ticker value near
overflow.

tests-mbed_hal-lp_ticker: change implementation of the delay before deep-sleep. ...

Serial buffer must be flushed before entering deep sleep mode. In the test this is done by the additional delay which is implemented on the busy loop which decrements given value down to 0 (`void wait_cycles(volatile unsigned int cycles)`). This solution is not appropriate since it is very target specific and the cycles value has been already increased few times. Additionally very big number of loop cycles which is suitable for fast targets may take much longer on slower boards and results in test timeout.
It has been verified that 20ms is sufficient delay for the green-tea transmission. In this test we cannot simply use `wait_ms(20)` since this potentially may put board to sleep and wake up using lp ticker. The test re-initialzies the lp ticker(disables ticker interrupt) and this operation may break the schedule and time tracing by the upper layer. But we can use us ticker which is not affected by this test. The solution is to add a delay routine based on busy loop and us ticker only. This way are able to wait exactly 20 ms.

tests-mbed_drivers-lp_timer: change delay method ...

The test sometimes fails on NRF51_DK (test case: "Test: LowPowerTimer - time measurement 1 ms.") in morph tests.

The test verifies if LowPowerTimer class correctly counts elapsed time. Sometimes we got measured ~1600 us for delay 1000 us (delta 550 us).
The delay is performed using `wait_us()` function which for delays greater than or equal to 1 ms (our case) calls `Thread::wait((uint32_t)ms);`. This causes rescheduling and potentially can put board into sleep (deep sleep mode is disabled by `wait_us()`). For our test purposes we don't need rescheduling/sleep since this actions takes extra time and have influence on the time measurement accuracy.
The solution is to implement function for delay which is based on busy loop and uses us ticker. It has been verified that this solves the problem. With this fix when measurement of 1 ms is repeated 1000 times we got usually measured time equal to ~1080 us, and sometimes ~1300us (checked that this is caused by systick interrupt handling). Since this is test for drivers layer and the results are acceptable I decided to not disabling systick in the test).
