clk: sprd: set max_register according to mapping range

Browse source

[ Upstream commit 47d4308653 ]

In sprd clock driver, regmap_config.max_register was set to a fixed value
which is likely larger than the address range configured in device tree,
when reading registers through debugfs it would cause access violation.
