power: qpnp-fg-gen4: Get charge pump enable status for ESR FCC config 



Currently, FG driver reads SMB_EN_MODE property to determine
whether charge pump is enabled or not for changing ESR FCC
configuration. This doesn't work well when the charge pump is
disabled. Instead of this, read cp_disable votable that indicates
the charge pump switcher status properly and make use of it for
changing ESR FCC configuration.
