[PATCH 2/3] arm64: dts: ls1012a: Add coreclk

ls1012a has separate input root clocks for core PLLs versus the platform
PLL, with the latter described as sysclk in the hw docs.
Signed-off-by: Scott Wood <oss at buserror.net>

Note that current versions of U-Boot are blindly updating the frequency
of all fixed-clock nodes. That needs to be fixed for the split input
frequency to work properly, but until U-Boot is fixed this change doesn't
make anything worse than it already was.
