Improve the coordinate and address alignment logic in the CO5300 display driver. The driver now properly aligns the framebuffer address according to the addr_align property from device tree, in addition to ensuring coordinates are even values.

Backport 4626c0e from #105901.
Original PR description:
The CO5300 display controller of zc143ac72mipi shield requires the start coordinate and the size(width/height) of the updated area to be even for each frame update. Also the DCNano DBI controller on MIMXRT700 EVK which performs the frame update requires the frame buffer address to be 64-byte aligned. So the CO5300 driver maintains an internal buffer, for each write, the update area are copied to the internal buffer first, then the descriptor shall be adjusted to the even value AND make sure the the address of the actual updated area are aligned properly.
Fixes #104000
