pitft: Add PiTFT22 support
- Add support to build overlays for PiTFT22 in the kernel. - Setup a basic configuration for the driver The PiTFT22 support is optional and can be enabled by adding below in local.conf: MACHINE_FEATURES += "pitft pitft22" This patch also includes restructuring of kernel patches per kernel version specific directories. [Support #70] Signed-off-by: Petter Mabäcker <petter@technux.se> Signed-off-by: Andrei Gherzan <andrei@gherzan.ro>
