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')

In the Linux kernel definitions of data structures should occur in .c
files. Hence move the exynos7_uic_attr definition from a .h into a .c
file. Additionally, declare exynos_ufs_drvs static. This patch fixes the
following two sparse warnings:
drivers/scsi/ufs/ufs-exynos.h:248:28: warning: symbol 'exynos_ufs_drvs' was not declared. Should it be static?
drivers/scsi/ufs/ufs-exynos.h:250:28: warning: symbol 'exynos7_uic_attr' was not declared. Should it be static?

Use common device parameter initialization function instead of initializing
those parameters by vendor driver itself.

This patch introduces Exynos UFS host controller driver which mainly
handles vendor-specific operations including link startup, power mode
change and hibernation/unhibernation.
