While at it, remove the MTK_PMIC_RST_DU_{MASK,SHIFT} definitions, as these can be expressed with the GENMASK macro and a new name was chosen for that, as to uniform the definition names with the others found in this driver. Lastly, it was necessary to change the function signature of mtk_pmic_keys_lp_reset_setup() to now pass a pointer to the main mtk_pmic_regs structure, since that's what contains the reset debounce mask now and, for readability purposes, for this function, all of the references to keys->regmap were changed to use a local 'rmap' pointer, or the calls to regmap_{set,clear}_bits would be ~94 columns long. This commit brings no functional changes.
