ANDROID: vendor_hooks: printk ignore the loglevel to pstore

Usually, we use the console-ramoops in pstore to check printk logs
during a reboot issue.
However, enabling the printk log level for the console
to investigate kernel and/or driver reboot issues sometimes delays
real-time processing.
As a result, the software behavior changes, and other problems may
occur instead.
To address this, we add a hook that allows us to send printk logs
to pstore while ignoring the log level.
We might be able to avoid using a vendorhook here if upstream has
the capability to record all levels of printk logs into pstore,
even if it is no longer called console-ramoops.
