Since commit 67694c076bd7 ("soc: loongson2_pm: add power management
support"), the Loongson-2K PM driver was added, but it didn't update the
Kconfig entry for the INPUT dependency, leading to build errors:
/opt/crosstool/gcc-13.2.0-nolibc/loongarch64-linux/bin/loongarch64-linux-ld:

Also, since this driver can only be built-in, it fails to link when the
INPUT is in a loadable module, so we should update the Kconfig entry to
depend on INPUT=y.
