firmware: imx: scu-pd: add specifying the base of domain name index support
As the domain resource id in the same type may not be continuous, so it's hard to describe all such power domains with current struct imx_sc_pd_range. Adding the optional base for domain name index to address this issue. Then we can add the discrete domains easily later.
