Like in IPQ6018 the NSS related Alpha PLL-s require initial configuration
to work.

So, obtain the regmap that is required for the Alpha PLL configuration
and thus utilize the qcom_cc_really_probe() as we already have the regmap.
Then utilize the Alpha PLL configs from the downstream QCA 5.4 based
kernel to configure them.

This fixes the UBI32 and NSS crypto PLL-s failing to get enabled by the
kernel.
