[PATCH] arm64: zynqmp: Remove ltc2954 node

Remove already disabled node. GPIO connections are handled by pmufw that's
why there is no reason to have it described for non secure firmware.
If someone wants to handle it from OS revert this patch and also update
PMUFW configuration and pinctrl setting for these GPIO pins.
