[PATCH v2 0/3] can: Kconfig: add missing COMPILE_TEST

[Vincent Mailhol <mailhol.vincent@wanadoo.fr>]

The ti_hecc and tscan1 CAN drivers can not be built on an x86_64
platform. Add the COMPILE_TEST dependency to allow build testing.

Doing that, a so far unnoticed W=0 warning showed up in ti_hecc. Fix
this warning. To prevent any potential noise in some future git
bisect, the warning is fixed before introducing COMPILE_TEST.

Note that the mscan and mpc5xxx drivers have the same issue but those
two use some helper functions, such as in_8() and out_8(), which are
only available on the powerpc platform. Those two drivers would
require some deeper code refactor to be built on x86_64 and are thus
left out of scope.
