Implement ARM errata 814220 for Cortex A7.
This patch has been wroten by Jason Liu years ago but never send upstream.
I have tried to contact the author on multiple email addresses but I haven't
found any valid one...
I have keep Jason's sign-off and just rebase the patch on to v5-rc6.

Since CEC framework enable and disable the adapter when it is needed
just follow it orders to enable/disable the clocks.
Call stm32_cec_hw_init() when the adapter is enabled and do not let
regmap manage registers clock help to simplify clocking scheme.

Add bindings information for STM32 Timers
version 6:
- rename stm32-gtimer to stm32-timers
- change compatible
- add description about the IPs
version 2:
- rename stm32-mfd-timer to stm32-gptimer
- only keep one compatible string

IIO device attribute) which internal signal (counter enable, reset,
comparison block, etc...) is used to generate the trigger.
