Now that their kernel clocks are described as CK_KER_STM and CK_KER_ETR, and as the RCC bus clock of the ETR is already CK_BUS_ETR, these names are confusing. They also differ from the reference manual and from the STM32MP21 binding, which uses CK_BUS_STM, CK_SCMI_BUS_ETR and CK_SCMI_BUS_STM for the same clocks. Use CK_BUS_STM, CK_SCMI_BUS_ETR and CK_SCMI_BUS_STM, with unchanged values, and keep the old names as deprecated aliases so that the existing users are not affected. No functional change.
