Clock and reset controller use same compatible strings (same IP).
Since commit 989eafd0b6 ("clk: core: Avoid double initialization of
clocks") the OF core flags clock controllers registered with the
CLK_OF_DECLARE() macro as OF_POPULATED, so platform devices with the same
compatible string will not be registered.

This patch adds the QSPI clock for stm32f469 discovery board.
The gate mapping is a little bit different from stm32f429 soc.

This patch introduces the support of the RTC clock.
RTC clock can have 3 sources: lsi, lse and hse_rtc.

This patch introduces the support of the LSI & LSE clocks.
The clock drivers needs to disable the power domain write protection
using syscon/regmap to enable these clocks.

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.

We're removing struct clk from the clk provider API, so switch
this code to using the clk_hw based provider APIs.

If stm32f4_rcc_lookup() is called with primary == 0 and secondary == 192
then it will read beyond the end of the table array due to an out-by-one
error in the range check.
In addition to the fixing the inequality we also modify the r.h.s. to
make it even more explicit that we are comparing against the size of
table in bits.

The driver supports decoding and statically modelling PLL state (i.e.
we inherit state from bootloader) and provides support for all
peripherals that support simple one-bit gated clocks. The covers all
peripherals whose clocks come from the AHB, APB1 or APB2 buses.
It has been tested on an STM32F429I-Discovery board. The clock counts
for TIM2, USART1 and SYSTICK are all set correctly and the wall clock
looks OK when checked with a stopwatch. I have also tested a prototype
driver for the RNG hardware. The RNG clock is correctly enabled by the
framework (also did inverse test and proved that by changing DT to
configure the wrong clock bit then we observe the RNG driver to fail).
