This driver is a platform driver. The probe function can be called after
kernel init, and try to reference kernel memory that has been freed.
Drop the __init markings everywhere here to avoid referencing initdata
from non-init code. Fixes modpost warnings.

Fixes: 6c81966107dc ("clk: hisilicon: Add clock driver for hi3559A SoC")
