fpu: Replace int8 typedef with int8_t
Replace the int8 softfloat-specific typedef with int8_t. This change was made with find include hw fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\bint8\b/int8_t/g' together with manual removal of the typedef definition, and manual undoing of various mis-hits. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
