maoxiaochuan 17d323e4e2 watchdog: loongson2: fix .remove callback return type mismatch 
Since Linux 6.11 (commit 0ed03dd1f63f), the platform_driver .remove
callback returns void instead of int. ls2x_wdt_remove still returns int,
triggering an -Werror=incompatible-pointer-types build error at the
.remove = ls2x_wdt_remove assignment.

Change ls2x_wdt_remove's return type to void and drop the return 0.

maoxiaochuan 139ba8bfee watchdog: loongson1: Add Loongson-2k0300 watchdog support 
According to the manual, the Loongson-2K0300 watchdog is similar to the
Loongson-1, except for some register offsets and inconsistent register
bit definitions. Separate definitions via driver_data suffice.

The general recommendation is to not use of_match_ptr() or CONFIG_OF
ifdef.

Drop them.
