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 fdb1bffe28 ("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.
