Add new defines for constant voltage shift (RT5033_CHGCTRL2_CV_SHIFT), MIVR mask (RT5033_CHGCTRL4_MIVR_MASK), pre-charge current shift (RT5033_CHGCTRL4_IPREC_SHIFT), internal timer disable (RT5033_INT_TIMER_DISABLE), termination disable (RT5033_TE_DISABLE), CFO disable (RT5033_CFO_DISABLE), UUG disable (RT5033_CHARGER_UUG_DISABLE). The fast charge timer type needs to be written on mask 0x38 (RT5033_CHGCTRL3_TIMER_MASK). To avoid a bit shift on application, change the values of the timer types to fit the mask. Added the timout duration as a comment. And the timer between TIMER8 and TIMER12 is most likely TIMER10, see e.g. RT5036 [1] page 28 bottom. Add value options for MIVR (Minimum Input Voltage Regulation). Move RT5033_TE_ENABLE_MASK to the block "RT5033 CHGCTRL1 register", in order to have the masks of the register collected there. To fit the naming scheme, rename it to RT5033_CHGCTRL1_TE_EN_MASK. Move RT5033_CHG_MAX_CURRENT to the block "RT5033 charger fast-charge current". Add new defines RT5033_CV_MAX_VOLTAGE and RT5033_CHG_MAX_PRE_CURRENT to the blocks "RT5033 charger constant charge voltage" and "RT5033 charger pre-charge current limits". In include/linux/mfd/rt5033.h, turn power_supply "psy" into a pointer in order to use it in devm_power_supply_register().
