Fix issue with MBED_11 test (mbed2)

[bcostm]

Description

• The MBED_11 test was failed/unstabled on our test bench since mbed revision 153 / mbed-os-5.6.2
• It was due to the use of printf inside ticker callback. Replacing it with RawSerial solved the issue
• More discussion in PR Remove wait in MBED_11 test (mbed 2) #5842 (closed)
