b62132392d stm32h735g: Use a intermediate line vector in the RAM for rendring 
It is much faster than blending on the frame buffer which is in hyperram

0c97cb0fcc Enable the data cache for stm32h7 
This requires us to flash the cache before swapping the frame buffer pointer.

With slide puzzle span drawing with image tiles goes from ~100ms down to ~50ms,
and theme switching between simple and berlin from ~140ms to ~72ms.

This is with the line renderer.

b7b1101adb Bump system clock frequence on stm32h735 
Up to 400 Mhz seems to work. Also fixed assert to match the octospi controller for the hyperram (1 instead of 2).
