Remove non standard API

fpistm · fpistm · commit c5017df708ca · 2018-09-19T14:55:17.000+02:00
delayInsideIT() code should have been in the method: void GSM3SoftSerial::tunedDelay(uint16_t delay) It was introduced as an API to support built-in GSM library on Nucleo-L476RG and is not relevant for other. Fix #250 Signed-off-by: Frederic.Pillon <frederic.pillon@st.com>
