If I drop the first two, I get some kconfig warnings:

WARNING: unmet direct dependencies detected for CLK_R9A06G032
   Depends on [n]: CLK_RENESAS [=n]
   Selected by [y]:
   - ARCH_RZN1 [=y] && <choice>

And there is no output on the UART.

Okay, I will try moving it. Does this also then mean I should abandon 
ARCH_RZN1 in favour of ARCH_RMOBILE? This could be more challenging...

Done!
