ls1012a has separate input root clocks for core PLLs versus the platform
PLL, with the latter described as sysclk in the hw docs.

Update the qoriq-clock binding to allow a second input clock, named
"coreclk".??If present, this clock will be used for the core PLLs.

'clk' part is redundant.

"sysclk" is a term used by the hardware documentation and I'd rather leave it
intact. ?"coreclk" isn't named (only described) by the hardware documentation
but it is a special variant of sysclk and having similar naming helps make
that clear.
