ARM: dts: am437x-sk-evm.dts: fix LCD timings
The lcd0 node for am437x-sk-evm.dts contains bad LCD timings, and while
they seem to work with a quick test, doing for example blank/unblank
will give you a black display.
This patch updates the timings to the 'typical' values from the LCD spec
sheet.
Also, the compatible string is completely bogus, as
"osddisplays,osd057T0559-34ts" is _not_ a 480x272 panel. The panel on
the board is a newhaven one. Update the compatible string to reflect
this. Note that this hasn't caused any issues, as the "panel-dpi"
matches the driver.
