[PATCH v4 8/8] dt-bindings: stm32: use reference manual names for ETR and STM bus clocks

[Gabriel Fernandez <gabriel.fernandez@foss.st.com>]

The bus clocks of the STM and of the ETR are identified by CK_BUS_STM500,
CK_SCMI_STM500 and CK_SCMI_ETR. 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.
