Subject: [PATCH] mediatek: mt7622: initialize watchdog after DDR init
Initializing the WDT before memory calibration breaks reboot at least
on some MT7622 boards like the Bananapi BPi-R64:
NOTICE: BL2: v2.7(release):OpenWrt v2022-08-18-9c9c4994-2 (mt7622-emmc-2ddr)
NOTICE: BL2: Built : 04:00:25, Aug 27 2022
ERROR: Cannot find any pass-window
ERROR: no DATLAT taps pass, DATLAT calibration fail!
ERROR: DATLAT calibration fail, write back to 20!
ERROR: EMI: complex R/W mem test failed: -2
Move watchdog initialization to happen only after memory initialization
has completed to avoid the problem.
