Subject: [PATCH v3] reset: qcom-aoss: Allow CONFIG_RESET_QCOM_AOSS to be a tristate

Allow CONFIG_RESET_QCOM_AOSS to be set as as =m to allow for the
driver to be loaded from a modules.

Also replaces the builtin_platform_driver() line with
module_platform_driver() and adds a MODULE_DEVICE_TABLE() entry.
