ARM: zii-imx51-rdu1: Use -fno-tree-switch-conversion -fno-jump-tables
Original and very poor workaround no longer works against GCC8, so
drop it and replace with a proper solution that should've been used in
the first place - specifying -fno-tree-switch-conversion
-fno-jump-tables as CFLAGS when building lowlevel.c
Tested to work with:
- GCC 8.2.1 (arm-none-eabi)
- GCC 7.1.0 (arm-none-eabi)
- GCC 4.8.4 (armv7l-timesys-linux-gnueabihf)
