clk: stm32mp1: fix rcc mckprot status

MCKPROT hardening in RCC mandates that both bits RCC[TZEN] and
RCC[MCKPROT] are enabled. This change fixes stm32mp1_rcc_is_mckprot()
to check both bits, not RCC[MCKPROT] only.

This change also updates stm32mp1_rcc_is_secure() for consistency.

drivers: stm32mp1 clocks: support shifted clock selector bit masks

The current implementation optimizes memory consumed by gateable
clock table by storing bit mask and bit shift with 1 byte each.
The issue is that register selector bit masks above the 7th LSBit
cannot be stored.

This change uses the shift info to shift the mask before it is used,
allowing clock selector register bit fields to be spread on the 32 bits
of the register as long as the mask fits in 8 contiguous bit at most.

This change is needed to add the RTC clock to the gateable clocks table.

clocks supported by this look up. This changes adds PLLs and other
system clocks. This enables for flexible use of clock tree exploration
when computing a clock frequency value.

plat/stm32: Implement fdt_read_uint32_default() as a wrapper

The STM32 platform code uses its own set of FDT helper functions,
although some of them are fairly generic.

Remove the implementation of fdt_read_uint32_default() and implement it
on top of the newly introduced fdt_read_uint32() function, then convert
all users over.

This also fixes two callers, which were slightly abusing the "default"
semantic.

plat/stm32: Use generic fdt_read_uint32_array() implementation

The device tree parsing code for the STM32 platform is using its own FDT
helper functions, some of them being rather generic.
In particular the existing fdt_read_uint32_array() implementation is now
almost identical to the new generic code in fdt_wrappers.c, so we can
remove the ST specific version and adjust the existing callers.

Compared to the original ST implementation the new version takes a
pointer to the DTB as the first argument, and also swaps the order of
the number of cells and the pointer.

All other configurations should be handled in Linux drivers requiring it.

Device tree files are also updated to manage vdd-supply regulator.

clk: stm32mp1: use defines for mask values in stm32mp1_clk_sel array

Rework the macro that eases the table definition: the src and msk fields
are now using MASK and SHIFT defines of each source register.
Some macros had then to be modified: _USART1_SEL, _ASS_SEL and _MSS_SEL to
_UART1_SEL, _AXIS_SEL, and _MCUS_SEL to match register fields.

Note: the mask for RCC_ASSCKSELR_AXISSRC is changed from 0x3 to 0x7
to reflect the size of the register field, even if there are only
3 possible clock sources.

The mask value is also corrected for QSPI and FMC clock selection.
