mfd: ti_am335x_tscadc: Update logic in CTRL register for 5-wire TS

Browse Source 
The logic in AFE_Pen_Ctrl bitmask in the CTRL register is different for five
wire versus four or eight wire touschscreens. This patch should fix this for
five-wire touch screens. There should be no change needed here for four and
eight wire tousch screens.
