ARM: dts: imx53-qsb: Fix regulator constraints
commit e3c9d9d6ebfeeeee29c6240e1b5978d40d31d21f upstream. Since commit fa93fd4ecc9c ("regulator: core: Ensure we are at least in bounds for our constraints") the imx53-qsb board populated with a Dialog DA9053 PMIC fails to boot: LDO3: Bringing 3300000uV into 1800000-1800000uV The LDO3 voltage constraints passed in the device tree do not match the valid range according to the datasheet, so fix this accordingly to allow the board booting again. While at it, fix the other voltage constraints as well.
