[ARM] vfp: fix fuitod/fsitod instructions
These two instructions exceptionally take a single precision register as their operand. This means we can't use vfp_get_dm() to read the register number - we need to use vfp_get_sm() instead. Add a flag to indicate this exception to the general rule. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
