Re: [PATCH v2 2/3] Input: goodix - use string-based chip ID

For Goodix GT917S chip, the chip ID string is "917S", which contains
not
only numbers now.

Use string-based chip ID in the driver to support this chip and
further
chips with alphanumber ID.

Changes in v2:
- Used a table to save ID and chip data info.
- Use strscpy().
