i2c: mediatek: fix WRRD for SoCs without auto_restart option
MediaTek mt65xx family SoCs have no auto restart, however, they still
support the WRRD mode in the hardware. Because auto_restart is set to 0,
the WRRD mode will be never enabled, leading to read errors.

Fix this by removing auto_restart check from the WRRD enable path.
