This framework only manages enabling and disabling regulators.
Peripheral drivers have to register their regulator with
stm32mp_regulator_register function, which calls plat_get_regulator.
This function has to be defined at platform level, to bind the
regulator ops depending on the regulator ID.
The functions stm32mp_regulator_enable and stm32mp_regulator_disable
can then be called inside drivers to manage their regulators.

For SD-cards, CMD6 is used to switch functions, like setting high speed
mode. As it has another meaning for eMMC, and may not work on standard
capacity SD-cards, it must be checked with MMC_IS_SD_HC flag.
As ACMD6 is also used, and will have the same index, a check on CMD/ACMD
commands is done: a boolean is stored depending on previous command. It is
set to true if CMD55 is issued, for other commands it is set to false.

On SD-cards, Switch Function Command (CMD6) is used to switch functions,
like setting High Speed mode. It is useful for high capacity cards to
double frequency (from 25MHz by default to 50MHz).
If the SD-card is High Capacity, a CMD6 is issued after filling the device
information. If High Speed mode is supported and the switch is OK, then
the max_bus_freq can be set to 50MHz. The driver set_ios function should
then be called to update peripheral configuration, especially clock
prescaler.
