arm64/pinephone: Add driver for Frame Buffer
This PR adds the Frame Buffer Driver for PINE64 PinePhone. With this
driver, NuttX Apps will be able to use the standard Frame Buffer API to render
graphics on PinePhone.
`boards/arm64/a64/pinephone/src/pinephone_bringup.c`: Render Test Pattern
after calling `up_fbinitialize()` to start the Frame Buffer Driver
`boards/arm64/a64/pinephone/src/pinephone_display.c`: Add Frame Buffer
Driver
`boards/arm64/a64/pinephone/src/pinephone_display.h`: Declare new function
for rendering Test Pattern
`platforms/arm/a64/boards/pinephone/index.rst`: Add Frame Buffer as
supported driver for PinePhone
