[PATCH 5/9] clk: bd718xx: Drop BD70528 support

[Matti Vaittinen]

The only known BD70528 use-cases are such that the PMIC is controlled
from separate MCU which is not running Linux. I am not aware of
any Linux driver users. Furthermore, it seems there is no demand for
this IC. Let's ease the maintenance burden and drop the driver. We can
always add it back if there is sudden need for it.

Please let me know if some of you think the driver is needed.
