During clock's registration, clock's name are used to establish parent - child relation. On STM32MP13 and STM32MP25, most of SCMI clocks are parent clocks.Since commit fdb1bffe2827 ("clk: scmi: Postpone clock name resolution"), all scmi clocks are named by default "scmi-%zu" until they are enabled, it breaks clocks registration and boot process for STM32MP13/25 platforms. Rework the STM32 core clock driver and STM32MP13/25 clock description to use clock index instead of their real name. Introduce struct clk_parent_data which allows to identify parent clock either by index or by name. Name is only used for particular clocks provided by IP which are clock provider as i2s/i2s_ckin, usb0/ck_usbo_48m, and ltdc/ck_ker_ltdc. STM32_GATE() and STM32_COMPOSITE_NOMUX macros are updated in order to use parent clock index. As STM32MP13 supports both SPL and SCMI boot, keep using an array with clock's name for SPL.
