Better integration of SPI with DMA and IRQ. Using only 'End' IRQ. Perf could be improved by using 'Started' IRQ to prepare the next buffer while the current one is beeing sent.

[WIP] Max SPI speed reached (119ms for a full refresh. Theo max : 240*240*16 = 115.2ms) using IRQ and DMA.
Code needs some cleaning before integration.

Disable SPI, I²C, touch controller and display controller in sleep mode.
Re-enable them on wake up.
Remove delays that were not needed in st7889 driver.
Hopefully, it'll improve the battery life!
