Provide just enough bits (clocks, clocksource, uart) to allow a kernel

MACH_INGENIC selects SYS_SUPPORTS_ZBOOT_UART16550, so I wonder whether
arch/mips/boot/compressed/uart-16550.c needs updating for JZ4770 like
commit ba9e72c2290f ("MIPS: Fix build with DEBUG_ZBOOT and MACH_JZ4780")
does for JZ4780.

Otherwise the non-DT bits look reasonable (I've not really looked
properly at the DT):

I will fix it in a separate patch, if you don't mind.
