[PATCH 0/6] Restore boot for STM32MP13/STM32MP2 board family

[Patrice Chotard]

Commit fdb1bffe2827 ("clk: scmi: Postpone clock name resolution")
is breaking boot for STM32MP13/STM32MP2 family board.

The issue is due to registering clock with default name "scmi-%zu".
If one of these clocks has children clocks, it will generate an error
when trying to registers their child's clocks as shown below:

...
clk_register: failed to get ck_axi device (parent of qspi_k)
clk_register: failed to get pll4_p device (parent of spi2_k)
clk_register: failed to get pll4_p device (parent of spi3_k)
clk_register: failed to get ck_hsi device (parent of usart3_k)
clk_register: failed to get ck_hsi device (parent of uart5_k)
clk_register: failed to get ck_hsi device (parent of uart7_k)
...

Re-introduce scmi_clk_get_attribute() call in scmi_clk_probe()
under a new flag CLK_SCMI_FORCE_ATTRIBUTE to register parent clocks
with their real names (ck_axi, pll4_p, ck_hsi ...)

This new flag CLK_SCMI_FORCE_ATTRIBUTE is enabled in stm32mp13_defconfig,
stm32mp23_defconfig and stm32mp25_defconfig to restore boot.

It will preserve the boot time optimization goal of the series [1]
