[v7,3/8] dt-bindings: clock: Add ids for Lynx 10g PLLs

Commit Message

This adds ids for the Lynx 10g SerDes's internal PLLs. These may be used
with assigned-clock* to specify a particular frequency to use. For
example, to set the second PLL (at offset 0x20)'s frequency, use
LYNX10G_PLLa(1). These are for use only in the device tree, and are not
otherwise used by the driver.
