Subject: [PATCH v2] net: can: Disable 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.
Disable the build for ARM on big endian CPUs.

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

v2: Instead of marking the build as broken, disable it for big endian ARM CPUs.
    Adjust headline accordingly.
