hw/ide/ahci.h: Avoid shifting left into sign bit
Add 'U' suffixes to avoid undefined behaviour shifting left into the signed bit of a signed integer type. Clang's sanitizer will warn about this: hw/ide/ahci.c:1210:27: runtime error: left shift of 1 by 31 places cannot be represented in type 'int' Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
