arm64: dts: ti: k3-j784s4-main: Align watchdog clocks

assigned-clock sets DEV_RTIx_RTI_CLK(id:0) whereas clocks sets
DEV_RTIx_RTI_CLK_PARENT_GLUELOGIC_HFOSC0_CLKOUT(id:1)[1]. This does not
look right, the timers in the driver assume a max frequency of 32kHz for
the heartbeat (HFOSC0 is 19.2MHz on j784s4-evm).

With this change, WDIOC_GETTIMELEFT return coherent time left
(DEFAULT_HEARTBEAT=60, reports 60s upon opening the cdev).
