bus: moxtet: Mark the irq as shared

commit e7830f5a83e96d8cb8efc0412902a03008f8fbe3 upstream.

The Turris Mox shares the moxtet IRQ with various devices on the board,
so mark the IRQ as shared in the driver as well.

Without this loading the module will fail with:
  genirq: Flags mismatch irq 40. 00002002 (moxtet) vs. 00002080 (mcp7940x)
