[PULL 16/36] target/arm: Use uint32_t in vfp_exceptbits_from_host()

[Peter Maydell]

In vfp_exceptbits_from_host(), we accumulate the FPSR flags in
an "int", and our return type is also "int". However, the only
callsite returns the same information as a uint32_t, and
more generally we handle FPSR values in the code as uint32_t,
not int. Bring this function in to line with that convention.

There is no behaviour change because none of the FPSR bits
we set in this function are bit 31. The input argument to
the function remains 'int' because that is the return type
of the softfloat get_float_exception_flags().
