Chen-Yu Tsai 01a7ea763f clk: sunxi-ng: r40: Force LOSC parent to RTC LOSC output 
On the R40, in addition to a mux between the RTC's own RC oscillator and
an external 32768 Hz crystal, which are muxed inside the RTC module, the
CCU also has its own RC oscillator, which runs at around 2 MHz, and can
be muxed with the LOSC output from the RTC. This muxed output is called
"SYS 32K" in the module clock diagram, but otherwise referred to as the
LOSC throughout the CCU documentation.

The RC oscillator is not very accurate, even though it has an undocumented
calibration function. We really want a precise clock at 32768 Hz,
instead of something at around 32 KHz. This patch forces the SYS 32K
clock to use the RTC output as its parent, and doesn't bother
registering the internal oscillator nor a clock mux.
