stm32 patches for v2019.07-rc1
- Add trusted boot with TF-A for stm32mp1
- stm32mp1 dts files sync'ed with Linux version
- add STM32MP1 Discovery boards (DK1 and DK2)
- add STMFX gpio expander driver
- misc improvement for stm3mp1 supports
- rename stpmu1 to stpmic1 (official name)
- stm32_qspi: move to exec_op (spi nor driver for stm32 mpu and mcu)
- add STM32 FMC2 NAND flash controller driver

Support for STM32MP SoC family developed by STMicroelectronics,
MPUs based on ARM cortex A core
U-BOOT is running in DDR and SPL support is the unsecure First Stage
BootLoader (FSBL)
U-BOOT is running in DDR, loaded by the First Stage BootLoader (FSBL).
FSBL can be TF-A: Trusted Firmware for Cortex A, for trusted boot
chain.
SPL is the unsecure FSBL for the basic boot chain.
