- Add various STM32MP1 fixes for serial, env, clk, board, i2c ...

- Add STM32MP1 DDR driver update:
	These update introduce the DDR interactive mode described in:
	https://wiki.st.com/stm32mpu/index.php/U-Boot_SPL:_DDR_interactive_mode

	This mode is used by the CubeMX: DDR tuning tool.
	https://wiki.st.com/stm32mpu/index.php/STM32CubeMX

	The DDR interactive mode is NOT activated by default because
	it increase the SPL size and slow down the boot time
	(200ms wait added).

This patch adds devicetree support to the mcfuart.c driver
and removes non DM code.

For STM32MP, the watchdog is based on DM and the function watchod_reset
call the function uclass_get_device(UCLASS_WDT) to found the driver
associated IWDG2.

As this reset is not mandatory in debug putc (the  uart fifo will be
empty after some us), we can simplify the code by removing this call.

And this patch avoid issue when putc is called before initialization
of DM core, before the parsing of the device tree parsing and each
node bound to driver; that also avoid memory leak.

- A10 FPGA programming support, Gen5 livetree conversion

Convert 'altera_uart_ofdata_to_platdata' to use 'dev_read_u32_default'
instead of 'fdtdec_get_int' and get rid of DECLARE_GLOBAL_DATA_PTR.

This CPU core is old, no boards using the CPU are left in mainline,
it has no prospects of ever being converted to DM, drop it.
