Remove Tickless from STM32F4 targets 

Ticless on STM32 F4 boards causes SPI issue with following PR:
# 11682 Make FPGA tests to pass on CI targets (SPI, analogIn, PWM)

In asynch mode, using interrupts, SPI hardware detect an RX overrun.
Our understanding is that lpticker wrapper latency
causes issue similar to #8714 and #9785,
specially with SPI asynch which use interrupts.
