Torin Cooper-Bennun 2712625200 can: tcan4x5x: tcan4x5x_init(): fix initialization - clear MRAM before entering Normal Mode 
This patch prevents a potentially destructive race condition. The
device is fully operational on the bus after entering Normal Mode, so
zeroing the MRAM after entering this mode may lead to loss of
information, e.g. new received messages.

This patch fixes the problem by first initializing the MRAM, then
bringing the device into Normale Mode.

Fixes: 5443c226ba ("can: tcan4x5x: Add tcan4x5x driver to the kernel")
