Within the current sunxi clk structure, the LOSC is registered as a fixed
32.768 KHz clk. So this patch actually makes things right.

In this case it should still be addressed somewhere in drivers/clk/sunxi, not 
in drivers/rtc, I guess? Would you prefer setting the external 32.768 KHz crystal
as hard coded default instead of providing the muxer? It could be considered okay,
for the data sheet seems to demand presence of the external oscillator and there
is absolutely no use in a 32KHz +- 20% oscillator, if a 32.768KHz crystal is
available.

Yes, poking into the registers in drivers/clk would also work.
