STM32MP1 chip embeds a dual Cortex-A7 and a Cortex-M4.
The support for Cortex-M4 clocks is added when configuring the clock tree.
Some minimal security features to allow communications between A7 and M4
are also added.

Regulator configuration at boot takes more information from DT.
I2C configuration from DT is done in I2C driver.
I2C driver manages more transfer modes.
The min voltage of buck1 should also be increased to 1.2V,
else the platform does not boot.

Heavily modifies stm32_i2c.c since many functions move inside the source
file to remove redundant declarations.

Previously the GICv3 redistributor probe function
(gicv3_rdistif_base_addrs_probe()) asserted that the number of
per-CPU redistributor interfaces expected to be probed by the
platform is equal to the number exported by the redistributor
frame. This is a problem in case the number of CPUs in the
platform is less than the number of redistributor interfaces
in the frame. Hence this patch removes the assertion check
and allows probe for fewer redistributor interfaces as required
by the platform.

Method cpld_reset_cpu of bl31 is called from the Linux kernel and uses
GPIO6, GPIO2 pins as SPI bus lines to control the CPLD device. But in the
kernel GPIO6_8 pin are initialized to work in interrupt mode instead of
the input/output mode. This leads to the fact that the SPI bus becomes
non-functional. In this patch we switch the GPIO6_8 pin back to the
input-output mode.
