phy: qcom: qmp-usbc: Move reset config into PHY cfg

Browse Source 
The original reset list only works for USB-only PHYs. USB3DP PHYs require
different reset names such as "dp_phy", so they need a separate list.

Moving reset configuration into qmp_phy_cfg allows per-PHY customization
without adding special-case logic in DT parsing. The legacy DT path keeps
using the old hardcoded list, while non-legacy paths use cfg->reset_list.
