Use board_get_usable_ram_top() instead of get_effective_memsize() to
set gd->ram_top to something <= 4GiB.
Both board_get_usable_ram_top() and get_effective_memsize() are used to
set gd->ram_top in setup_dest_addr(). However, get_effective_memsize()
also sets gd->bd->bi_dram[0].size in dram_init_banksize(), which is
undesirable.
Prior to commit bddd6bbef3dc ("arm: mediatek: mt7988:
drop dram_init_banksize()"), gd->bd->bi_dram[0].size was overridden in
a board-specific dram_init_banksize() implementation. When that was
removed get_effective_memsize() set gd->bd->bi_dram[0].size to the wrong
value because of CFG_MAX_MEM_MAPPED.
Rather than continue to use an old-style CFG_ option and the potentially
confusing overriding of gd->bd->bi_dram[0].size (it is difficult to see
which order the functions that set it are called), we can just use
board_get_usable_ram_top() to set gd->ram_top to the correct value
instead. This is possible now, thanks to LMB_LIMIT_DMA_BELOW_RAM_TOP
being set by default for 64-bit Mediatek ARM SoCs.
The CFG_MAX_MEM_MAPPED option is removed since it is no longer needed.
The config header and Kconfig option are also removed since that was
the last CFG_ option.

Commit 86acdce2ba88 ("common: add config for board_init() call")
introduced CONFIG_BOARD_INIT option. This option can be disabled for the
boards where board_init() function is not needed. Remove empty
board_init() calls for all boards where it's possible, and disable
CONFIG_BOARD_INIT in all related defconfigs.
This cleanup was made semi-automatically using these scripts: [1].
No functional change, but the binary size for the modified boards is
reduced a bit.

This patch adds general board files based on MT7988 SoCs.
MT7988 uses one mmc controller for booting from both SD and eMMC,
and the pins of mmc controller booting from SD are also shared with
one of spi controllers.
So two configs are need for these boot types:
1. mt7988_rfb_defconfig - SPI-NOR, SPI-NAND and eMMC
2. mt7988_sd_rfb_defconfig - SPI-NAND and SD
