586701cece refactor(st-i2c): use fdt_read_uint32_default()
The function stm32_i2c_get_setup_from_fdt() was using fdt_getprop() to
to get some i2c node properties, and set a default value if the node
was not found. The function fdt_read_uint32_default() already does
this in a simpler way.
Remove useless STM32_I2C_SPEED_DEFAULT.

Replace calls to stm32mp_clk_enable() / stm32mp_clk_disable() /
stm32mp_clk_get_rate() with clk_enable() / clk_disable() /
clk_get_rate().

d82d4ff066 stm32mp1: update I2C and PMIC drivers
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.
