[PATCH v1] riscv: dts: microchip: add can resets to mpfs

[Conor Dooley <conor@kernel.org>]

From: Conor Dooley <conor.dooley@microchip.com>

The can IP on PolarFire SoC requires the use of the blocks reset
during normal operation, and the property is therefore required by the
binding, causing a warning on the m100pfsevp board where it is default
enabled:
mpfs-m100pfsevp.dtb: can@2010c000 (microchip,mpfs-can): 'resets' is a required property
Add the reset to both can nodes.
