Subject: [PATCH 1/2] dt-bindings: qoriq-clock: Add coreclk

From: Tang Yuantian <redacted>

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.
