Subject: [PATCH] net: can: Disable broken flexcan driver build for big endian CPU on ARM

Building arm:allmodconfig fails with

flexcan.c: In function 'flexcan_read':
flexcan.c:243:2: error: implicit declaration of function 'in_be32'
flexcan.c: In function 'flexcan_write':
flexcan.c:248:2: error: implicit declaration of function 'out_be32'

in_be32 and out_be32 do not (or no longer) exist for ARM targets.
Mark the build for arm on big endian CPUs as broken.

Signed-off-by: Guenter Roeck <linux@...ck-us.net>

If there is a better solution, please let me know and I'll be happy
to provide a patch.
