This patch adds the support of reset and clock control
block (rcc) found on STM32 SoCs.
This driver is similar to a MFD linux driver.
This driver supports currently STM32H7 only.
STM32F4 and STM32F7 will be migrated to this rcc MFD driver
in the future to uniformize all STM32 SoCs already upstreamed.
This driver implements basic clock setup, only clock gating
is implemented.
This driver doesn't implement .of_match as it's binded
by MFD RCC driver.
Files include/dt-bindings/clock/stm32h7-clks.h and
doc/device-tree-bindings/clock/st,stm32h7-rcc.txt
will be available soon in a kernel tag, as all the
bindings have been acked by Rob Herring [1].

retrieve the base-addresses of GRF and SGRF. After that, we use
the structure definitions to locate the respective registers.

- all headers are included at the beginning (there was a spurious
inclusion of the grf header from within a function)
- all #include statements for unused headers are removed
- the remaining #include statements are sorted (while keeping common.h
included in front)
