can: flexcan: flexcan_chip_freeze(): fix chip freeze for missing bitrate
For cases when flexcan is built-in, bitrate is still not set at
registering. So flexcan_chip_freeze() generates:
[ 1.860000] *** ZERO DIVIDE *** FORMAT=4
[ 1.860000] Current process id is 1
[ 1.860000] BAD KERNEL TRAP: 00000000
[ 1.860000] PC: [<402e70c8>] flexcan_chip_freeze+0x1a/0xa8
To allow chip freeze, using an hardcoded timeout when bitrate is still
not set.
Fixes: ec15e27cc890 ("can: flexcan: enable RX FIFO after FRZ/HALT valid")
