_ Add gpio compatible and aliases for stm32f429

_ Add FMC sdram node with associated new bindings value to manage second bank (ie bank 1).

_ Add "u-boot,dm-pre-reloc" for rcc, fmc, fixed-clock, pinctrl, pwrcfg and gpio nodes.

STM32F4 SoCs uses the same pinctrl block as found into STM32F7 and H7 SoCs. We can add "st,stm32f429-pinctrl" and "st,stm32f469-pinctrl" compatible string into pinctrl_stm32.c.

This allows to support rcc MFD driver. By enabling all these flags, we need to increase malloc area to avoid crash during early stage.

Remove serial_stm32.c driver and uart init from board file, use available DM serial_stm32x7.c driver compatible for STM32F4/F7 and H7 SoCs.

The serial_stm32x7.c driver will be renamed later with a more generic name as it's shared with all STM32 Socs.

Use available DM clk_stm32f.c driver instead of dedicated mach-stm32/stm32f4/clock.c.

Migrate periph_clock defines from stm32_periph.h directly in CLK driver. These periph_clock defines will be removed when STMMAC, TIMER2 and SYSCFG drivers will support DM CLK.

Enable also CLK flag.

From: Patrice Chotard patrice.chotard@st.com

Use available DM stm32f7_gpio.c and pinctrl_stm32.c drivers instead of board GPIO initialization.

Remove stm32_gpio.c which is no more used and migrate structs stm32_gpio_regs and stm32_gpio_priv into arch-stm32f4/gpio.h to not break compilation.

This allows to controls the memory internal mapping at address 0x0000 0000. We can either map at 0x0000 0000 : _ main flash memory _ system flash memory _ FMC bank1 (NOR/PSRAM 1 and 2) _ embedded SRAM _ FMC/SDRAM bank1

This is needed for future STM32F469-disco board
