boards/arm/stm32h7: add WeAct STM32H750 board support
This commit introduces complete support for the WeAct STM32H750
development board, including board configuration, linker scripts, and
drivers for NSH, SD card, ST7735 LCD, SPI, USB, and other peripherals.
All necessary files and configurations are added to enable building and
running NuttX on this STM32H7-based board.

+/* The STM32H750VB has 128Kb of main FLASH memory. The flash memory is
+ * partitioned into a User Flash memory and a System Flash memory. Each
+ * of these memories has two banks:
+ *
+ * 1) User Flash memory:
+ *
+ * Bank 1: Start address 0x0800:0000 to 0x080F:FFFF with 8 sectors, 128Kb
each
+ * Bank 2: Start address 0x0810:0000 to 0x081F:FFFF with 8 sectors, 128Kb
each
+ *
+ * 2) System Flash memory:
+ *
+ * Bank 1: Start address 0x1FF0:0000 to 0x1FF1:FFFF with 1 x 128Kb sector
+ * Bank 1: Start address 0x1FF4:0000 to 0x1FF5:FFFF with 1 x 128Kb sector
+ *
+ * 3) User option bytes for user configuration, only in Bank 1.
+ *
+ * In the STM32H750VB, two different boot spaces can be selected through
+ * the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
+ * BOOT_ADD1 option bytes:
+ *
+ * 1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
+ * ST programmed value: Flash memory at 0x0800:0000
+ * 2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ * ST programmed value: System bootloader at 0x1FF0:0000
+ *
+ * TODO: Check next paragraph with nucleo schematics
+ *
+ * NuttX does not modify these option bytes. On the unmodified NUCLEO-H743ZI
+ * board, the BOOT0 pin is at ground so by default, the STM32 will boot
+ * to address 0x0800:0000 in FLASH.
+ *
+ * The STM32H750VB also has 1024Kb of data SRAM.
+ * SRAM is split up into several blocks and into three power domains:
+ *
+ * 1) TCM SRAMs are dedicated to the Cortex-M7 and are accessible with
+ * 0 wait states by the Cortex-M7 and by MDMA through AHBS slave bus
+ *
+ * 1.1) 128Kb of DTCM-RAM beginning at address 0x2000:0000
+ *
+ * The DTCM-RAM is organized as 2 x 64Kb DTCM-RAMs on 2 x 32 bit
+ * DTCM ports. The DTCM-RAM could be used for critical real-time
+ * data, such as interrupt service routines or stack / heap memory.
+ * Both DTCM-RAMs can be used in parallel (for load/store operations)
+ * thanks to the Cortex-M7 dual issue capability.
+ *
+ * 1.2) 64Kb of ITCM-RAM beginning at address 0x0000:0000
+ *
+ * This RAM is connected to ITCM 64-bit interface designed for
+ * execution of critical real-times routines by the CPU.
+ *
+ * 2) AXI SRAM (D1 domain) accessible by all system masters except BDMA
+ * through D1 domain AXI bus matrix
+ *
+ * 2.1) 512Kb of SRAM beginning at address 0x2400:0000
+ *
+ * 3) AHB SRAM (D2 domain) accessible by all system masters except BDMA
+ * through D2 domain AHB bus matrix
+ *
+ * 3.1) 128Kb of SRAM1 beginning at address 0x3000:0000
+ * 3.2) 128Kb of SRAM2 beginning at address 0x3002:0000
+ * 3.3) 32Kb of SRAM3 beginning at address 0x3004:0000
+ *
+ * SRAM1 - SRAM3 are one contiguous block: 288Kb at address 0x3000:0000
+ *
+ * 4) AHB SRAM (D3 domain) accessible by most of system masters
+ * through D3 domain AHB bus matrix
+ *
+ * 4.1) 64Kb of SRAM4 beginning at address 0x3800:0000
+ * 4.1) 4Kb of backup RAM beginning at address 0x3880:0000
+ *
+ * When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
+ * where the code expects to begin execution by jumping to the entry point in
+ * the 0x0800:0000 address range.

+ * Input Parameters:
+ * arg - The boardctl() argument is passed to the board_app_initialize()
+ * implementation without modification. The argument has no
+ * meaning to NuttX; the meaning of the argument is a contract
+ * between the board-specific initialization logic and the
+ * matching application logic. The value could be such things as a
+ * mode enumeration value, a set of DIP switch switch settings, a
+ * pointer to configuration data read from a file or serial FLASH,
+ * or whatever you would like to do with it. Every implementation
+ * should accept zero/NULL as a default configuration.
+ *
+ * Returned Value:
+ * Zero (OK) is returned on success; a negated errno value is returned on
+ * any failure to indicate the nature of the failure.
