Update hy28b-overlay.dts

My hy28b TFT stopped working on upgrade to 5.4 kernel.  I had a whitescreen but no obvious errors when using 'sudo vcdbg log msg' or 'dmesg'.  Both /dev/fb0 and /dev/fb1 were present.  Followed this article on waveshare32b that 'reset_gpios needed to be 0 0 1 instead of 0 0 0' (https://forum.armbian.com/topic/13233-any-clues-for-the-creation-of-a-dtoverlay-for-fbtft-on-54y/).  I applied a similar change to this dts file and compiled a new dtbo: 'dtc -O dtb -o hy28b.dtbo hy28b-overlay.dts'.  Fixed my issue - may help others?  I got from the 5.4 upgrade thread that other tft users are having issues with small tfts... https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=269769&p=1706597&hilit=gpio#p1706597
