arm64/pinephone: Add driver for LCD Panel (Xingbangda XBD599)
This PR adds the driver for Xingbangda XBD599 LCD Panel (based on Sitronix ST7703 LCD Controller) on PINE64 PinePhone. This PR also includes: - The driver for X-Powers AXP803 Power Mgmt IC, which calls our driver for Allwinner A64's Reduced Serial Bus. The PMIC Driver is needed to power on the MIPI DSI Interface for the LCD Panel. - A simple Display Driver that renders a Test Pattern on the LCD Display at startup. It calls our Allwinner A64 drivers for Display Engine, Timing Controller TCON0 and MIPI Display Serial Interface. The NuttX Frame Buffer Driver will be implemented in the next PR. `arch/arm64/src/a64/a64_de.c`, `a64_de.h`: Changed the Frame Buffer pointer to `const` for Allwinner A64 Display Engine `arch/arm64/src/a64/hardware/a64_memorymap.h`: Added the Base Address for PWM, for controlling the PWM Backlight `boards/arm64/a64/pinephone/src/pinephone_bringup.c`: Call `fb_register()` to start the Display Driver at startup `boards/arm64/a64/pinephone/src/Makefile`: Added LCD Driver, PMIC Driver and Display Driver to Makefile `boards/arm64/a64/pinephone/Kconfig`: Added the Kconfig option for "PINE64 PinePhone > LCD Display" (`CONFIG_PINEPHONE_LCD`) which enables the LCD Driver, PMIC Driver and Display Driver `boards/arm64/a64/pinephone/src/pinephone_lcd.c`, `pinephone_lcd.h`: Driver for Xingbangda XBD599 LCD Panel `boards/arm64/a64/pinephone/src/pinephone_pmic.c`, `pinephone_pmic.h`: Driver for X-Powers AXP803 Power Mgmt IC `boards/arm64/a64/pinephone/src/pinephone_display.c`: Simple Display Driver that renders a Test Pattern in `up_fbinitialize()` `boards/arm64/a64/pinephone/configs/lcd/defconfig`: New PinePhone Board Configuration `pinephone:lcd` that enables the LCD Driver (`CONFIG_PINEPHONE_LCD`) `platforms/arm/a64/boards/pinephone/index.rst`: Added PinePhone Board Configuration `pinephone:lcd` that enables the LCD Driver
