Signed ARM_SMCCC_FAST_CALL value is shifted to 31'st bit. Then, it is expanded
to 64 bit value, which results in 1s in higher 32 bits.
This causes corrupted values in 64-bit SMC IDs and issues in buggy handlers of
32-bit calls.
We need to make ARM_SMCCC_FAST_CALL unsigned long, so it would work properly
on 32 bit architectures.
