can: tcan4x5x: Remove invalid write in clear_interrupts
Register 0x824 TCAN4X5X_MCAN_INT_REG is a read-only register. Any writes to this register do not have any effect. Remove this write. The m_can driver aldready clears the interrupts in m_can_isr() by writing to M_CAN_IR which is translated to register 0x1050 which is a writable version of this register.
