Justin Hammond 78dfefa4cc boards/risc-v/eic7700x: Adopt the common board layout.
The port had one board directory holding one board, with everything in it
whether it described the SoC or the PCB.  A second EIC7700X board follows,
so this adopts the common-plus-board layout NuttX provides, as mpfs uses.

boards/risc-v/eic7700x/common holds what is true of the SoC: the boot path
that mounts the RAM disk and /proc before calling the board's own bring
up, the linker script, the start up scripts and the image builder.
ARCH_CHIP_EIC7700X selects ARCH_BOARD_COMMON, so the symlinks the build
makes always point at code that compiles.

The board directory keeps what is a fact about the PCB: its own board.h
and board_memorymap.h, since the include fallback is all or nothing, a
bring up that owns the order its devices register in, and a board_config.h
declaring what that bring up may call.

The image builder moves to common/tools and derives its output name from
the configuration.  It computes the padding between the kernel and the RAM
disk from _ebss rather than assuming 64 KiB, which fails once BSS grows
past it: the disk lands below _ebss and the BSS clear zeroes it before
anything searches for it.

The StarPro64 configuration gains what the port now needs: four harts,
960 MiB of RAM, a larger task stack, a backtrace on assert, the system log
in RAM for dmesg, and ELF applications, for which ARCH_CHIP_EIC7700X now
selects ARCH_HAVE_ELF_EXECUTABLE.

board.h loses its LED definitions.  CONFIG_ARCH_LEDS is not set, nothing
implements board_autoled_on(), and the indices they gave named no LED.

The documentation pages gain the tags the template asks for.
