media: imx274: rename and reorder register address definitions
Most registers are defined using the name used in the datasheet. E.g. the defines for the HMAX register are IMX274_HMAX_REG_*. Rename the SHR and VMAX register accordingly. Also move them close to related registers: SHR close to SVR, VMAX close to HMAX.
