- Drop MMCI interrupt-names in STM32H743, STM32MP15 and STM322MP13 DT

Browse source 
DHSOM:
   - Enable assorted ST specific commands
   - Add version variable
   - Add boot counter
 STM32MP13:
   - Add sdmmc cd-gpios for STM32MP135F-DK
   - Add clock & reset support
 STM32 ADC:
   - Split channel init into several routines
   - Add support of generic channels binding

* ------------------------------ ----------
* Each peripheral requires a bus interface clock, named ckg_bus_perx
* (for peripheral ‘x’).
* Some peripherals (SAI, UART...) need also a dedicated clock for their
* communication interface, this clock is generally asynchronous with respect to
* the bus interface clock, and is named kernel clock (ckg_ker_perx).
* Both clocks can be gated by one Perx_EN enable bit.
* Then we have to manage a refcounting on gate level to avoid gate if one
* the bus or the Kernel was enable.
*
* Example:
* 1) enable the bus clock
 * --> bus_clk ref_counting = 1, gate_ref_count = 1
 * 2) enable the kernel clock
 * --> perx_ker_ck ref_counting = 1, gate_ref_count = 2
 * 3) disable kernel clock
 *  ---> perx_ker_ck ref_counting = 0, gate_ref_count = 1
 *  ==> then i will not gate because gate_ref_count > 0
 * 4) disable bus clock
 * --> bus_clk ref_counting = 0, gate_ref_count = 0
 * ==> then i can gate (write in the register) because
* gate_ref_count = 0
