pmdomain: mediatek: mtk-mfg: select MAILBOX in Kconfig

The mtk-mfg pmdomain driver calls common mailbox framework functions. If
the common mailbox framework is not selected in the kernel's
configuration, the build runs into a linker error, as the symbols are
absent.

The hardware mailbox Kconfig system, MAILBOX, has no dependencies of its
own. It's therefore safe to "select" it rather than use "depend on".

Declare this "select" dependency in the Kconfig for the driver.
