[PATCH v2 1/2] power/reset: at91-reset: add samx7 support

[Alexandre Belloni]

From: Szemző András <sza@esh.hu>

Add samx7 support. It is lacking a few bits and needs a new reset function.

[PATCH v2 2/2] power/reset: at91-reset: remove leftover platform_device_id

[Alexandre Belloni]

commit eacd8d09db7f ("power/reset: at91-reset: remove useless
at91_reset_platform_probe()") removed non DT probe support but forgot to
remove the now useless id_table. Do that now.
