Subject: [PATCH] dtoverlays: Add invx and invy overrides to ads7846 touch
overlay
It had swapxy, but no way to trigger the X and Y inversions
Also use the generic "touchscreen-swapped-x-y" for swapxy
instead of the TI specific "ti,swap-xy".

penirq is required and usually xohms (60-100) has to be set as well.
Apart from that, pmax (255) and swapxy are also common.
