can: flexcan: assert FRZ bit in flexcan_chip_freeze()
commit 449052cfebf624b670faa040245d3feed770d22f upstream.
Assert HALT bit to enter freeze mode, there is a premise that FRZ bit is
asserted. This patch asserts FRZ bit in flexcan_chip_freeze, although
the reset value is 1b'1. This is a prepare patch, later patch will
invoke flexcan_chip_freeze() to enter freeze mode, which polling freeze
mode acknowledge.
