Subject: [PATCH 0/2] ARM: stm32: add clock for pwrcfg syscon

The STM32F4/7 pwrcfg syscon was missing its clock, making it impossible
to use after clk_disable_unused(). Simply adding the clock creates a
circular dependency, because the syscon is used by the clock driver.
This series resolves this dependency and then adds the clock.

I tested this on a STM32F746 and verified that syscon writes now
succeed even after clk_disable_unused().

  clk: stm32: initialize syscon after clocks are registered
