dt-bindings: timer: fsl,imxgpt: Add optional osc_per clock
Since commit bad3db104f89 ("ARM: imx: source gpt per clk from OSC for
system timer") osc_per can be used for clocking the GPT which is not
scaled when entering low bus mode.
This clock source is available only on i.MX6Q (incl. i.MX6QP) and i.MX6DL.
