[PATCH][next] net: dsa: microchip: make read-only array ts_reg static const

[Colin Ian King]

Don't populate the read-only array ts_reg on the stack at run time,
instead make it static const.

## Form letter - net-next-closed

The net-next tree is closed for new drivers, features, code refactoring
and optimizations due to the merge window and the winter break. We are
currently accepting bug fixes only.

Please repost when net-next reopens after Jan 2nd.

RFC patches sent for review only are obviously welcome at any time.
