STM32F769 clocks are derived from STM32746 clocks.
main differences are:
- new source clock for SAI1 and SAI2 (HSI or HSE)
- Add DFSDM & DSI clocks

The failure path in the newly added function tries to free an
uninitialized pointer:
drivers/clk/clk-stm32f4.c: In function 'stm32f4_rcc_init':
drivers/clk/clk-stm32f4.c:1106:4: error: 'gate' may be used uninitialized in this function [-Werror=maybe-uninitialized]
I'm adding an initialization to NULL here to make the kfree()
succeed, and I'm also rearranging the cleanup so that the
same kfree() is used for any error path, making the function
slightly more robust against newly introduced bugs in the
error handling.

Clock and reset controller use same compatible strings (same IP).
Since commit 989eafd0b6 ("clk: core: Avoid double initialization of

CLK_OF_DECLARE() macro as OF_POPULATED, so platform devices with the same
compatible string will not be registered.

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.

Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
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).
