clk: qcom: clk-alpha-pll: Add support for common PLL configuration function
To properly configure the PLLs on recent chipsets, it often requires more
than one power domain to be kept ON. The support to enable multiple power
domains is being added in qcom_cc_really_probe() and PLLs should be
configured post all the required power domains are enabled.
Hence integrate PLL configuration into clk_alpha_pll structure and add
support for qcom_clk_alpha_pll_configure() function which can be called
from qcom_cc_really_probe() to configure the clock controller PLLs after
all required power domains are enabled.
