Subject: [PATCH v3 0/3] toshiba_acpi: Fix USB Sleep & Charge mode and documentation updates

This patch fixes the USB Sleep & Charge charging mode on certain
models, fixes pr_* messages and also adds the missing entries in the
documentation file.

Changes since v2:
- Check for TOS_SUCCESS to initialize and flag as supported on first
patch

Changes since v1:
- Set the default supported value of sleep and charge to zero in case
of an error and added comments.
- Updated the title and commit message of second patch to better
reflect what the patch is doing.

Subject: [PATCH v3 1/3] toshiba_acpi: Update and fix USB Sleep and Charge modes

This patch fixes the USB Sleep and Charge mode on certain models
where the value returned by the BIOS is different, and thus, making
this feature not to work for those models.

Also, the "Typical" charging mode was added as a supported mode.
