Input: mtk-pmic-keys - transfer per-key bit in mtk_pmic_keys_regs

Browse Source 
Place the key bit in struct mtk_pmic_keys_regs to enhance this
driver's flexibility, in preparation for adding support for more
PMICs.

While at it, remove the definition of MTK_PMIC_RST_KEY_MASK as
we are now dynamically setting the keymask relatively to the keys
that are defined in the newly added rst_en_mask variable, on a
per-key basis.

This commit brings no functional changes.
