davinci: omapl138_lcdk: fix tXSNR DDR2 timing value
As per the datasheet[1] available for DDR2 part on board
the OMAP-L138 LCDK, the tXSNR (exit self refresh to a
non-read command) is 137.5 ns. This corresponds to a
value of 20 to be written to T_XSNR register field of
OMAP-L138's DDR configuration. The DDR2 is at 150 MHz.
Fix this. The correct value also appears on the initialization
scripts (called CCS GEL files) available on TI's wiki pages[2]
