can: c_can: don't cache TX messages for C_CAN cores
As Jacob noticed, the optimization introduced in 387da6bc7a82 ("can:
c_can: cache frames to operate as a true FIFO") doesn't properly work
on C_CAN, but on D_CAN IP cores. The exact reasons are still unknown.
For now disable caching if CAN frames in the TX path for C_CAN cores.
Fixes: 387da6bc7a82 ("can: c_can: cache frames to operate as a true FIFO")
