The 'iprop' variable is passed as an argument to the be32_to_cpup()
function, which expects a 'const _be *' type.

Change the iprop variable type so that the following build warnings
with W=1 are gone:

sound/soc/fsl/fsl_utils.c:72:40: warning: incorrect type in argument 1 (different base types)
sound/soc/fsl/fsl_utils.c:72:40:    expected restricted __be32 const [usertype] *p
sound/soc/fsl/fsl_utils.c:72:40:    got unsigned int const [usertype] *[assigned] iprop
sound/soc/fsl/fsl_utils.c:80:32: warning: incorrect type in argument 1 (different base types)
sound/soc/fsl/fsl_utils.c:80:32:    expected restricted __be32 const [usertype] *p
sound/soc/fsl/fsl_utils.c:80:32:    got unsigned int const [usertype] *[assigned] iprop
