ARM: dts: omap5-cm-t54: fix ldo1_reg and ldo4_reg ranges
ldo4_reg is connected to DSS, and should always be 1.8V. However the The dts defines a range of 1.5V-1.8V, which requires somethings to set the actual voltage at runtime. Currently we set the voltage in omapdss driver. As the voltage must always be 1.8V, let's just define the range to 1.8V so that the driver doesn't need to deal with the voltage. In fact, the driver should not touch the voltage, except in the cases where the voltage needs to be changed at runtime. I presume the situation is the same for ldo1_reg, used for CSI, although I think it is not currently used in the mainline.
