[v3,0/2] clk: add assigned-clock-rates-u64

Message

i.MX95 PLL VCO supports rates that exceeds UINT32_MAX, and the
i.MX95 System Controller Management Firmware(SCMI) server exports
PLL VCO for SCMI Agents to configure. So introduce
assigned-clock-rates-u64 to support rates that exceeds UINT32_MAX.
And introduce of_property_for_each_u64 to iterate each u64 rate.

The PR to add assigned-clock-rates-u64 to dt-schema has been merged:
https://github.com/devicetree-org/dt-schema/pull/140

Changes in v3:
- Add R-b for patch 1
- Rewrite patch 2 to avoid duplicated code. Patch 2 not use code from
  patch 1 now, but since patch 1 is a helper, so keep it.
- Link to v2: https://lore.kernel.org/r/[e-mail]

Changes in v2:
- Follow what Luca did to of_property_for_each_u32 to write of_property_for_each_u64
- Link to v1: https://lore.kernel.org/r/[e-mail]
