Subject: [PATCH 2/4] toshiba_acpi: Remove "*not supported" feature prints

Currently the driver prints "*not supported" if any of the features
queried are in fact not supported, let us print the available
features instead.

This patch removes all instances pr_info printing "*not supported",
and add a new function called "print_supported_features", which will
print the available laptop features.
