Subject: [PATCH v2 7/7] riscv: dts: microchip: add missing CAN bus clocks

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

The CAN controller on PolarFire SoC has an AHB peripheral clock _and_ a
CAN bus clock. The bus clock was omitted when the binding was written,
but is required for operation. Make up for lost time and add to the DT.
