Align dma buffers (#248)

* Do not loop forever

If the TPS65185 are unable to start the PWRGOOD signal will never assert.

* Align DMA buffers

The size of the buffers used by DMA must be word aligned. If the
width of the screen is not aligned we increase the buffer slightly.

Add epd_powerdown for lilygo (#179)

* added epd_powerdown

On lilygo disable display power but not touch screen.
  The epd power flag was re-purposed as power enable
   however it also disables the touch.
  this workaround may still leave power on to epd
  and as such may cause other problems such as grey screen.
  please also use poweroff when you sleep the system
  wake on touch will still work just not the I2C interface.

* lilygo epd_powerdown note in readme

Sorry it's not the prettiest thing.

* Documentation change

Deoxygenised the comments on the function so it will be explained in the readthedocs.io

* Clarify readme

* Finish readme  for lily go

* Clean up

* Oops
