The osc24M clock does not have a "clock-output-names" property, which
means that the clock name is derived from the node name in Linux. The
node name was changed in commit acfd5bbe2641 ("ARM: dts: sun6i: Change
clock node names to avoid warnings"). This breaks Linux as the sunxi-ng
clock driver implicitly depends on the external clock being named
"osc24M".
Add a "clock-output-names" property to restore the previous behavior.

warnings")

This is a critical fix for v5.0-rc. Without it the A31 boots up to the
UART failing to get its clock rate, and thus failing to setup a console.
Also the timer-sun5i init code hits a divide by zero exception. I'll
send a separate patch to make this one fail gracefully.
