[ Upstream commit 313bf281f2091552f509fd05a74172c70ce7572f ]

clk_get_rate() returns unsigned long and currently this driver stores the
return value in u32 type, resulting the below warning:

Fixed smatch warnings:

        drivers/scsi/ufs/ufs-exynos.c:286 exynos_ufs_get_clk_info()
        warn: wrong type for 'ufs->mclk_rate' (should be 'ulong')

        drivers/scsi/ufs/ufs-exynos.c:287 exynos_ufs_get_clk_info()
        warn: wrong type for 'pclk_rate' (should be 'ulong')
