fpu: Replace uint8 typedef with uint8_t

fpu: Replace uint8 typedef with uint8_t

Replace the uint8 softfloat-specific typedef with uint8_t.
This change was made with

find include hw fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\buint8\b/uint8_t/g'

together with manual removal of the typedef definition and
manual fixing of more erroneous uses found via test compilation.

It turns out that the only code using this type is an accidental
use where uint8_t was intended anyway...
