zephyr: Add support for CONFIG_FPU
Allow this to be enabled for Zephyr. Since we are using the minimal C
library we need to define our own version of a few functions. Add these
for Cortex-M4, taken from the existing ECOS code.
It happens that Zephyr uses CONFIG_FPU, the same as ECOS, so there is
nothing needed in config_chip.h for this case. If CONFIG_FPU is enabled
on a new platform, some work will be needed to make it build.
BUG=b:180023514
BRANCH=none
TEST=build zephyr volteer with CONFIG_NEWLIB_LIBC and see no warnings
Build for volteer
