Merge patch series "can: m_can: Optimizations for tcan and peripheral chips"

Markus Schneider-Pargmann <msp@baylibre.com> says:

as requested I split the series into two parts. This is the first
parts with simple improvements to reduce the number of SPI transfers.
The second part will be the rest with coalescing support and more
complex optimizations.
