riscv: dts: microchip: add can resets to mpfs

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.
