Changes in v5:
- Dropped initramfs from ci20_defconfig.
- Drop nowait from builtin command line in ci20_defconfig.
- Enable UARTs 0, 1, 3 & 4 (all of which are accessible on the board)
and specify their numbering using aliases to preserve their ttyS0,
ttyS1, ttyS3 & ttyS4 naming.
Changes in v4: None
Changes in v3:
- Rebase, relocating behind CONFIG_MACH_INGENIC.
Changes in v2: None
