Subject: [PATCH] dt-bindings: timer/rtc: Remove duplicate st,stih407-lpc bindings

The "st,stih407-lpc" binding is documented in 3 places as it can
function as a timer, watchdog, or RTC. As there's already a schema for
it in watchdogy/st,stih407-lpc.yaml, remove the other text bindings.

-STMicroelectronics Low Power Controller (LPC) - RTC
-===================================================
-
-LPC currently supports Watchdog OR Real Time Clock OR Clocksource
-functionality.
-
-[See: ../watchdog/st_lpc_wdt.txt for Watchdog options]
-[See: ../timer/st,stih407-lpc for Clocksource options]
-
-Required properties
-
-- compatible 	: Must be: "st,stih407-lpc"
-- reg		: LPC registers base address + size
-- interrupts    : LPC interrupt line number and associated flags
-- clocks	: Clock used by LPC device (See: ../clock/clock-bindings.txt)
-- st,lpc-mode	: The LPC can run either one of three modes:
-                  ST_LPC_MODE_RTC    [0]
-                  ST_LPC_MODE_WDT    [1]
-                  ST_LPC_MODE_CLKSRC [2]
-		 One (and only one) mode must be selected.
-
-Example:
-	lpc@...05000 {
-		compatible	= "st,stih407-lpc";
-		reg		= <0xfde05000 0x1000>;
-		clocks 		= <&clk_s_d3_flexgen CLK_LPC_0>;
-		st,lpc-mode	= <ST_LPC_MODE_RTC>;
-	};
