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.
