[net-next 1/6] can: tcan4x5x: remove mram_start and reg_offset from struct tcan4x5x_priv

[Marc Kleine-Budde <mkl@xxxxxxxxxxxxxx>]

Both struct tcan4x5x_priv::mram_start and struct tcan4x5x_priv::reg_offset are
only assigned once with a constant and then always used read-only. This patch
changes the driver to use the constant directly instead.
