- Use div64_ul() instead of div_u64() if the divisor is unsigned long,
to avoid truncation to 32-bit on 64-bit platforms,
- Use div_u64() for 64-by-32 divisions.

- Use div64_ul() instead of div_u64() if the divisor is unsigned long,
to avoid truncation to 32-bit on 64-bit platforms,
- Prefer ULL constant suffixes over casts to u64,
- Prioritize multiplication over division, to increase accuracy.

As of commit 362b334b17943d84 ("ARM: dts: r8a7791: Convert to new
CPG/MSSR bindings"), all upstream R-Car Gen2 device tree source files
use the unified "Renesas Clock Pulse Generator / Module Standby and
Software Reset" DT bindings.
Hence remove backward compatibility with old R-Car Gen2 device trees
describing a hierarchical representation of the various CPG and MSTP
clocks.

A NULL pointer would be passed to a call of the function kfree()
directly after a call of the function kzalloc() failed at one place.
Remove this superfluous function call.
This issue was detected by using the Coccinelle software.
