Subject: [PATCH v2 0/5] HSI0 and HSI2 support for Google Tensor gs101

This patch series enables the HSI0 and HSI2 (high speed interfaces) for
gs101:

- HSI0 feeds the USB block and is a prerequisite to get USB working.
- HSI2 feeds PCIe and UFS

The parts added here have been verified to work OK without the
clk_ignore_unused kernel command line option.

Changes in v2:
- My v1 just contained HSI0, but due due to changing similar areas in the
  code, I've also added Peter's HSI2 clock patches from
  https://lore.kernel.org/all/20240423205006.1785138-1-peter.griffin@linaro.org
  to this series so as to preempt any merge conflicts. Namely:
  * hsi2 bindings
  * hsi2 DT
  * hsi2 cmu clock driver
- drop patch 'dt-bindings: clock: google,gs101-clock: add HSI0 clock
  management unit' as already applied
- cometic updates to patch 4: 'clk: samsung: gs101: add support for
  cmu_hsi0' (macro name, a whitespace, subject line)
- Link to v1: https://lore.kernel.org/r/20240423-hsi0-gs101-v1-0-2c3ddb50c720@linaro.org
